We just finished up our stainless steel 3" downpipe on our cobalt ss/tc. We cnc'd both flanges in house for precise fitment with the stock components. It also features a flex section to allow for engine movement and daily abuse. The downpipe removes the restrictive factory catalytic converters.

Morgan will be putting the car on the dyno later today, look for those results here.

features:

-direct replacement no modifications required
-removes catalytic converters
-made in the USA
-madrel bent for free flow
-simple to install
-dyno results soon to follow

Introductory Special $299 shipped for cobaltss.net members.

notes:
*due to the removal of the catalytic converter, this downpipe is for off road use only, and not legal for use on US roadways.*

Looks good. What is it going to cost?

w000t way to go guys and getting the ball rolling quicking it seems the ss/tc is goiong to be huge in the aftermarket as far as gms go

What about CEL?

bumer... every day I feel like my lsj is being tarnished... Crys to himself! lol

Wow, that is very nice, but what about getting some DTC codes. Is there a tune to dissable the rear O2 sensor?

Wow, that is very nice, but what about getting some DTC codes. Is there a tune to dissable the rear O2 sensor?

tuning is still verrrrrryyyy limited....HP Tuners is working on the next update to be able to tune the TC tho which should allow the rear O2 sensor to be disabled.

Wow, that is very nice, but what about getting some DTC codes. Is there a tune to dissable the rear O2 sensor?

Not needed...
Look closely at the pictures, the rear O2 bung is extended to avoid setting off the CEL associated with the cat.

precisely.

we are still doing some testing, but we havent had any codes yet. when the hp tuner software becomes available there will be a lot more we can do with this car, including our gt3076r turbo upgrade.

introductory pricing on these will be $299 shipped.

Theres already tuning using the PPC module.

Very nice guys. Just curious, do you have any plans on making a downpipe w/ a cat?

Parts for the SS S/C would be nice as well... :lol:

lol, Us SC guys are old news man!

correct me if I'm wrong but the PPC handheld tuner isnt a user adjustable tuning solution, it simply flashes a preprogrammed map. we would need something we can tune for our exact kit.

quoted from Hahn

"It's plug and go, with one highly developed program. End-user tuning is not supported at this time. The Bosch DI controller is a very exotic and hugely sensitive system that's not yet equipped with end-user friendly options. So, we take all the stumbling and guesswork out of it."

can't wait to see some numbers

can't wait to see some numbers

++++1

will this bolt up to the hahn 3 in catback?

^^^ good question

because i am getting the hahn 3 inch catback

they said its meant to bolt up to the stock parts of the cobalts. so i dont see why it wouldnt

Sound Clippppp!!!!!

looks great, can't wait to see some #

Sound Clippppp!!!!!

x2!!

^^^ good question

because i am getting the hahn 3 inch catback

Me too.. im wondering if i should just get the 3 in. inlet or the Tc inlet.. i dotn know what the difference is???

bumer... every day I feel like my lsj is being tarnished... Crys to himself! lol

We have like 50 downpipes man , and enuff aftermarket for a wise person to build 400+ hp car now :lol:

Nice welds , that looks like a nice quality piece .

nvm I just seen the cat is gone... which is not legal in the US

so your point is....

yea, i run catless... the law ftl

so your point is....

He already mentioned the point.

But here it is again:

... not legal in the US

if the hahn 3" exhaust bolts up to the stock downpipe, it should bolt up to our downpipe. it is a direct replacement.

any dyno results yet?

our dyno appointment ran late last night we didnt have a chance to get it on the dyno. We're gonna try to get it on tonight after today's appointment.

He already mentioned the point.

But here it is again:

thank you

if the hahn 3" exhaust bolts up to the stock downpipe, it should bolt up to our downpipe. it is a direct replacement.

Does this downpipe bottle neck anywhere... like right before the flange does it go to 2.5 or is it just 3 in. pipe from flange to flange?

no bottleneck, 3" tubing from flange to flange

ooooooohhhhhhhhhhh shiney

Whats you site agian?

lol its his name

http://www.synapseturbo.com/


and I might have to purchase this for future references... I know I wanted to buy a turbo-back.. but with Hahn Cat-Back + This Downpipe... I will be closer to reaching my goal

whats your goal?

I'd like to see the dyno results................

whats your goal?

to get a turbo back exhaust... for when I put a Bigger turbo in

Here is the comparison graph from the stock downpipe to our downpipe still maintaining the stock catback exhaust/intake. As you can see there were consistant gains above 3500. With tuning I'm sure there are even more substantial gains to be had. We still have not had any check engine lights on the stock ECU for the secondary o2 sensor.

We do have some video footage i will try to get up later of the pulls and how the exhaust sounds(much better). Thanks for your interest in the downpipe. We will be selling these for an introductory special of $299 shipped. PM me for more information about downpipes with catalytic converters as i see many have shown interest in these.

Is this with just the DP, or does the car have your charge pipe on it still?

nice .. i see that it's still pretty limited to 260 trq but it definately helped out in the upper rpms as well as the lower (pre spool) rpms.. man i these ss/tc's are going to be pretty scweet i can't wait to see one with all hahns plans as well as your pd.. full turbo back exhaust, piping, intercooler, cai and a tune.. these things should be pretty quick.. once hptuners gets one the ball i forsee some 11 second balts with very little money into mods (compaired to how much it takes to get the ss/tc there)

Is this with just the DP, or does the car have your charge pipe on it still?

yes our charge piping is on the car.

heheheh
the ecm is still going
yesnoyesnoyesnoyesnoyesno

charge pipe... is what lets more air into the intercooler right?

sorry but what is a charge pipe? or is that another name for something?

they replaced the line from the turbo to I/C and I/C to throttle with larger piping (that they make)

there is a thread made by them floating around here somewhere w/ the details

heheheh
the ecm is still going
yesnoyesnoyesnoyesnoyesno
:lol:

Some more good news... I was talking with Bill from Hahn and he said that their 3 in. exhaust has an inlet with the 3 bolt flange and is completely 3 in, no bottleneck.

This in theory means that this downpipe should bolt right up to Hahns cat back!:cssNET:

Ill be giving Synapse a call today!

^^ yes if it bolts up to Hahn 3' Cat-Back I will also be buying one

i just got off the phone with my dealership

i can do ANYTHING i want to the car
they say if something mess up as long as its not the part that i added then it will be under warranty... they said if the part that i added mess up then I pay for it

:) so as soon as you are ready to ship them I am ready to pay

Just got off the phoen with Morgan at Synapse... I just ordered the DP and he said i should be recieving it late next week or early the following week:) I also have the Hahn 3 in. cat back coming my way too! When everything gets here I'll make a thread with lots o pics of the install, and hopefully i can find a video camera somewhere too.

I just ordered my DP too... same set up.. Synapse DP + Hahn 3' Cat Back

I am also looking at buying this setup. please let me know how the setup turns out. I want video clips with some dyno numbers before I drop 800+. cant wait!

I think my total came out to around 850 shipped for the DP and CB... I personally am very happy with my purchases considering this whole set-up retails for around 1050 not including shipping.

Pimplay, what are you trying to build the same exact car as me?:lol: Please don't tell me your ordering the charge piping too? In about a week ill be ordering that and whenever an intake comes out ill be getting that too. Along with HP tuners whenever the fuck that will come out.

lmao naw I never thought about the charge pipe... but I will be getting a Turbo Tech Intake whenever that comes out.. I wont be getting Hp tuners personally but I will have one of my tuning buddies tune my car from HP...

how much is charge pipe

600ish i think, maybe synapse would be willing to start a GP on it though? Maybe if we get say 10 people we could get it for around 500. Anyone down?

you know im down

Count me in on that also. But I dont follow the threads a lot. But now I have something to look for!

so we got 3... hmm time for a pm to synapse:twothumbs

The dyno numbers are already over in their other thread....

there are dyno numbers of the 3in down pipe into the hahn 3in catback?

So let me see

stock- 240whp
DP and CP- 255whp

so 15whp gains with lets say $800

what was the tq gains?

pretty much.. and people are bitching that the charge piping is too expensive.. people spend 600-1k on shit in an ss/sc bolt ons wise to get 15 hp ( intake, header and dp) and people are bitching because they think charge piping is a " bling mod" and don't know wtf they're talking about lol..

Dude.. i want my f'n downpipe!!!! It should be here some time this upcoming week. With this and my hahn CB, i wanna see if i can pop some flames with the no lift shift:guns:

well yea the DP will come first... but what r u goin to do install the DP then wait for Hahn to ship the CB like me.... or u goin to install the DP then wait for the CB?

Im going to wait and do it all at once. When the CB gets here im going to send both CB and DP to swaintech to get coated, then wrap the manifold, dp, and catback to the muffler. (Swaintech coating will only go to the muffler also) Then once that gets back I'm gonna get before and after video and pics and a how-to with pics of the install. Also gonna try and get a video of a flame if they shoot.

lmao shoot flames eh

You guys think with an intake, exhaust, and DP you will still be able to hear the spool?

You guys think with an intake, exhaust, and DP you will still be able to hear the spool?

you can hear the spool without any of them?
or
you mean from outside the car?

I said that thank you.

I am not a super genius but I am not stupid.

Why replace something that really isn't holding the car back?

Right now it is a bling mod, but there is some room to be gained from the top end...ECM limits TQ...but if you free shit up HP can be gained.

And correct me if I am wrong....TBE would be from the DP back wouldn't it?

:lol:

Stock I can hear the spool inside and outside the car. I was driving to work tonight and my Brother and his friend were riding next to me and they could hear it. I was just wondering because I wanna do exhaust now, and then get the intake later. But I dont wanna get the exhaust and then not be able to hear the spool. Its not that big of a deal, but I do like to hear that lovely sound. :)

Overall our cars will be relatively quiet without a cat and a decent cat back like Hahn's.


The turbo muffles a lot of sound naturally...look at how tiny the stock muffler is:lol:

You will always be able to hear the turbo, and throw a K&N drop in :cool: should help out

Ok, thanks for the info. I havent even looked at the stock exhaust, but I know I wanna replace it.

post video please :) im going to order it but I want to hear it first

Keep in mind the stock exhaust is not that restrictive. It is mandrel bent and has a straight through muffler design. The body of the muffler is large and has lots of packing to absorb sound and make the car quiet. That combined with the resonator and two cats make it really quiet. With our downpipe there is more sound but its not annoying or excessive.

here is the video from our dyno

http://www.youtube.com/watch?v=3YwrySNrHm8

nice 255whp.

:) and mine will be here soon

wow that exhaust sounds much better now.. i can't wait to hear a tc with dc, catback, intake, and charge piping that'll sounds sweet

wow that exhaust sounds much better now.. i can't wait to hear a tc with dc, catback, intake, and charge piping that'll sounds sweet

well i will have DP and CB on soon (I ordered both)... and when an intake comes out I will have that... I will be sure to post sound clips

i've seen u guys alot on the Honda forums, work looks quality.

all downpipes have shipped. thanks for the orders!

all downpipes have shipped. thanks for the orders!

One thing I ask Synapse...is to do a bi weekly dyno run.


See if the power stays without a tune.

I want these pretty parts that open things up, but without a tune it is pissing in the wind if eventually the ecm does de-tune it.

Just a thought

why does it sound like that at the end theres like no rev limiter it just sounds weird braaaaaahhh

the engine doesnt actually hit rev limiter, the dyno stops the engine dead in its track at whatever rpm you give it for a range. if you set the upper limits beyond the redline then the motor will hit the rev limiter and the dyno will still try to read, so you would end up with a chart that looks like this. the dyno is still trying to read the decel looks like the dyno was waiting to reach 8600rpm, and the rev limiter kicked in at 8588.

http://www.synapseturbo.com/gallery/cache/fe38072939f4322a3e22c1f4cd3430e57ab2cafd_800.jpg

wow, what the shit, the dyno does a freaking loop-the-loop @ 2250 rpm lol

that is most certainly not normal as it no longer counts as a mathmatical function

lol this isnt a mathematical function. it is a measurement. morgan apparantly let off the throttle a bit at that point.

Did you have the charge pipe installed when you dynod the DP?

downpipe installed yesterday. Threw a code 5 oclock today... lol

i dont like how this is going :lol: hopefully not anything like the last balt

yeah i know lol. im about to take it off and sell it

the code go away or its still there?

Installed mine today, install was a bitch on jackstands. And the three bolt flange is also a pain in the ass. Love the sound too, It's LOUD when you get on it above 3500. But at idle, under 3500, and downshifting are all a tiny bit louder then stock, which is perfect and it has a nice quiet burble to it.

No need for a catback in all honesty, It's plenty loud for the cops to look at you the wrong way, but only if you let them see it.

And i also have a CEL, but i'm going to try an O2 simulator and see if that solves the problem.

I am selling mine if any T/C is thinking of buying one

^^^ haha why? Just because a cel came on? It is such a worth it mod.:cssNET:

^^^ haha why? Just because a cel came on? It is such a worth it mod.:cssNET:

because I am going to get Hahn's Downpipe.... mind as well I am getting there cat-back

We are surprised the cel came on as we haven't gotten one on our car as of yet (100 miles). If you space the rear o2 out a little more with a simulator the cel should be gone. I am glad you like the sound, it gives the exhaust note a little more without being overwhelming.

because I am going to get Hahn's Downpipe.... mind as well I am getting there cat-back

when I install a downpipe I always space the rear 02 even if the company claims it already has. until hptuners is ready thats the only thing you can do. I have never had any cel when done this way. :cssNET:

With the Cel on did the computer make the car go into limp mode?

Hptuners is ready and the rear o2 can be disabled!

cool

Hptuners is ready and the rear o2 can be disabled!

are you sure about that?

Is there an o2 on the manifold, because i only saw one?

yea i was goin to ask the same question... i only seen one... i am putting my downpipe on tomorrow

I thought you were selling it? Either way you'll love the sound of it! It's loud when you get on it but quiet during a cruise:guns:

I thought you were selling it? Either way you'll love the sound of it! It's loud when you get on it but quiet during a cruise:guns:

I thought about selling and... then i figured hahn wont have one out for a while... so for not I will keep the damn thing... and just find something to disable the CEL

Since the DP are throwing an o2 code on most that have been ordered, we are going to send all those who have already purchased one of our downpipes and those who do in the future with an o2 simulator in the kit.

I hope this helps everyone out, its a great part as far as sound, and performance and we would all like to see everyone as happy as possible with our products.

Thanks everyone for their understanding and patience,

Synapse Motorsport inc.

when are these being sent out?

We will be sending them out this comming week, as soon as we get them they will ship out to everyone.

:) good I need that... even though I dont know what a simulator is lol... i know what it does though

Will this change the pricing of the kit?


This one was one of the reasons i didn't order one, and was just going to wait until someone sold theirs used. Then i would make a trip to radio shack and make my own simulator.

WOW..... i just installed mine... it sounds SOOOOOO GOOD

:eek: wow! now that's a good vendor. :twothumbs

SHIT=) NICE! Those things ain't cheap:lol: When do i get mine?:)

They cost about $5.. its an extender. Cool that the vendor offers it free. Should have been included in the first place, tho.

i dont think there talking about an extender they specifically said O2 simulator it's a resistor you install to fool the computer into thinking the cat is.....

1. there
2. functioning properly
3. no more cel


yes it cost about 5 dollars to make it if you know how many hz you need and know how to solder,

but it's a little more reliable then thee old extender (sparkplug defouler)

so yes great vendor to offer that which they sell for around $20 on ebay, but good old GM decides to make there run off a different hz frequency so the ones on ebay wont work... been there tried that...

^^ huh?

what dont you understand?

do you know what a O2 simulator is

ya but the synapse one doesnt come with one?

reading > you.... see post #106 my friend

SOUNDS GOOD!!

We are sending defoulers out, to space it out more, there will be no increase in price and they will be pre-drilled to our o2 sensor bodies so you can just screw it in. Thanks again guys, and iam glad you like the sound, it really wakens the cobalt up.

ya know those work well on other cars, but i have found that with the cobalt they are hit or miss some get cels some dont... of coarse it could have alot to do with the install and drilling of the de-fouler... but good luck

So if i order a downpipe how long would it be befor it gets here?? like are there some ready to be shipped

As as I said before - an extender. Its good that they are doing this tho..

Well i called in and ordered mine today. while talking to the guy he was talking about some of the things soon to come out. like im excited.. he said they are bring a front mount kit out soon. and are going to be working on an upgraded turbo kit... this company seems like a real good vendor too btw,,,

It will be one or the other. We finally got our cobalt to throw a code, so now we can troubleshoot the issue here, fix it and send out the proper fitting or simulator accordingly.

thanks for the order Mark. A fellow airman! im a Staff Seargant in the Air Force Reserves out of westover MA.

F1x0r it.

ANd yes I am following you around and will until you spill the beans:lol:

yep mine just threw a code today on my way home

When are you shipping out the 02 sims?

after throwing a check engine light last week, we installed our modified defouler, and we have put 500+ miles on it since then and have not thrown a check engine light. We are going to be sending these out within the next day or 2.

Cats are made mostly of paladium, a Russian heavy metal. specks of this stuff have been found on both the north and south poles. YES, That's right! the very cat used to supposedly clean the air is doing just the opposite! This has been found by independent scientists the world over. So the heck with cats. I took them off my 2006 GTO and the car actually smogged cleaner "without" than with them.

All the lower octane fuels, cats, and other stupid stuff is all governmental, revenue generating, political BS!

I took enough hours in Earth Biology\climate to tell you that the Earth has had 20+ ice ages over several billion years and in that time betweeen ice ages, the earth warms dramatically, then heads towards another cold snap, then another ice age. It's a natural occuring part of this planet and to mess with it or try to stop the process will make things worse not better. Mother earth has been dealing with a far dirtier more polluted planet millions of years ago than the way the atmosphere is now!, please! the ozone is cleaner now that i has ever been, and we need to stop tampering with it, she'll clean her self in time, THAT'S A FACT OF PAST HISTORY!,, BILLIONS OF YEARS WORTH OF HISTORY.

Not sure where that rant came from.. weird.

Stand behind a car with a cat and without. See which one chokes you.

^^^ yea dude i took my cat off and had my friend rev it and i thought i was goin to pass out

Wait till its 90 degrees outside and you're sitting at a light with the windows open. Not to mention, that stink stays on your clothes.. all day. Not cool if you work in an office.

holy fucking idiot batman!!!

Sure, you gain power, sure you throw flames.

True, you don't gain MUCH power, and true, throwing flames look bad ass.

I personally would never go catless again unless I own a turbo car.

holy fucking idiot batman!!!
global warming nut, are ya?


Are there any vids yet of what the ss/tc sounds like with stock exhaust and a the o/r downpipe?

IF I put the downpipe on my car, won't i have to retune it???:confused:

Why are you doin all that yellin? I bet you're not gellin.

^^ yes if it bolts up to Hahn 3' Cat-Back I will also be buying one

i just got off the phone with my dealership

i can do ANYTHING i want to the car
they say if something mess up as long as its not the part that i added then it will be under warranty... they said if the part that i added mess up then I pay for it

:) so as soon as you are ready to ship them I am ready to pay



ummm.. be careful. if you mess with the exhaust, that might void your turbo tho?

ummm.. be careful. if you mess with the exhaust, that might void your turbo tho?

Not necessarily....

A catless downpipe is questionable. A catback, not so much.

fuck the warrenty big turbo no cats FTW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

IF I put the downpipe on my car, won't i have to retune it???:confused:

when you change any part it is always recommended to tune the car to maximum gains. but the downpipe can be installed with the stock ECU.

Ok I have to know... What do you have done to the SS/TC to get it at the HP and torque in your sig?

installed our downpipe, turned the boost up, and tuned the car in house with HPtuners software.

so has anyone installed the downpipe with the Hahn Exhaust?? How does it sound? Any CEL come up when the hahn was installed

I hear Hahn is coming out with their own DP for the SS/TC. I know some owners are afraid to mix the two but I don't see anything wrong with it. I'd get the Synapse DP for sure! I'm also anxiously awaiting that turbo swap! :)

Does the word - LOUD come to mind?

i have the Snapse DP w/Hahn 3in cat-back installed on my T/C... It sounds AMAZING... you hear hahns DEEP DEEP GROWL while cruising then at WOT you hear Synapse D/P... Its awesome... and I have a CEL from the D/P still so I cant answer your last question

Does the word - LOUD come to mind?

i actually dont think its loud...... but I also did have a Dodge Charger R/T with long tube headers, Slp Loudmouth 1's, frank racing cam, and milled,ported and polished heads on so not much is "loud" to me on a 4banger lol

Loud with the Hahn exhaust and catless downpipe

Loud with the Hahn exhaust and catless downpipe

well i have both.... and still dotn think lol

I just put mine on today... it was like ez... love the sound... not too loud during normal driving...but sounds good when you get on it.. was a little expensive.... but thats what you get when you want something when a car just came out... i love it guys.. if you got a SS/TC get this haha

Turbos muffle sound, A LOT.

Have you ever heard a NSRT-4???? :lol:

Have you ever heard a NSRT-4???? :lol:

Yeah, that is all how the exhaust is made.

I have heard catless dp evo's that are quieter than Cobalts with the magnaflow exhaust.

were all the defoulers sent out??

Yes sir, they have been sent.

umm i still have a check engine light

Hey Synapse, I think you need to re-state your torque numbers as it's way to high!! 360 lb\ft of torque with the few things you've dont to the car is not possible

OMG

Sounds GOOD as fuck!

i want one but i dont want that annoying light

umm i still have a check engine light


Have you cleared the check engine light with a scanner and then installed the defoulor? It has taken care of the problem for us and many others.

If you don't clear the code it will stay on.

naw bro i never make videos... i dont own a camera lol.. i just own a Voyager that distorts sound like a bitch so u cant hear it

lol tru guess i will just have to buy it then :lol:

I have both the DP and hahn 3 in. and in all honesty the car was louder with a sp and stock exhaust. But with the hahn its not so loud that cops look at you and it sounds awsome. Like an exotic 4 cylinder, its nice and deep and still has enough sound to make people look at you. And it feels a little bit quicker. I can't wait to order HP tuners:guns:

^^ yea dude it makes ure exhaust more quite at WOT with Hahn but it is soooooooooo deep i love it... ppl say it sounds like i have a inline-6 or like a diesel truck lol

Hey Synapse...if you HPT you can just turn off p0420 eh?

yes you can turn off all the check engine lights in HPT individually. we dont have any disabled though.

So when's that GT3067R turbo swap going to be available? ;)

Already started saving for it... :lol:

Well our turbo came in today to start building our kit, but we decided to use something other than a 30r, for a little quicker spool and larger powerband.

um ZOMG HOLY SHIIIIIT

Oh? How much power are you guys expecting????

So how do you plan on getting past the 22.5 PSI wall?

So how do you plan on getting past the 22.5 PSI wall?

umm different turbo effeciency.. 22.5 psi could be around 400 whp on a different turbo. bigol red is running like 22 psi and is getting mid 300s ..

That would be sweet.

I would just expect more boost out of a turbo swap...not saying boost=power though

actually i lied .. bigol red in running a 3071 61r at 20 psi and ran 393whp and 380 trq on a mustang dyno ;)

Hmmm, I wonder how hard a turbo swap is:lol:

I know 22.5 psi is nice

i have not recieved my defouler...

i have not recieved my defouler...

it got returned to sender with usps. i'm going to be sending it out ups today.

I dont see there being room for a turbo upgrade and fighting the ECM monsters to make it run reliably.

GM really put this car together so no one could tamper with it or do aftermarket upgrades other than themselves. Talk about cornering the market. Any how, this DP is supposedly good for 15\15 at the wheels? That's about 20\20 at the brake\ crank, That should be power you'll feel and see on the speedo\tach, but most have said it's just a sound change. 50 hp is the comon incriment used to calculate drops\quicker 0-60 mph and quarter times. I don't mean to deviate so much, but on my 2006 GTO they had the LS2 from the vett with 400\400. I threw some bolt-ons in and the power went to 448\440 my quarter mi dropped by half a sec and my 0-60 mph also went from about 4.9 sec to 4.5 sec. Same can be said about the SS\TC. the HPT and PPC add about 40-50 hp and people are runing half a sec faster if not more and 3-5 mph faster than stock as compared to the mags tests. Lots of people are telling me that a DP will make a noticable improvement in power from the mid and upper ends of the rpms. What do the rest of you think? I'm not adding exhausat as it's perfectly good till 360+ hp so I'm told. Feel free to add to this Synapse.

My dash hawk says I went from stock 0-60 in 5.68 sec with PPC it's 5.1 sec. with spinning tires, so say about 4.9 sec with some grip. This is huge. Keedp the goodies coming Synapse.

there are solstices and sky's running around with big turbo swaps and 400 + whp... hell theres a kit that brings it to 390 whp

^^^^^Now that would be nice!!! I know Synapse and Hahn are working on some goodies to that effect but? we'll see how they do. 400 whp with sticky tires in a sky\solst!!!!? that's = 2008 C6 Z06 level acceleration in a car that's about 190 lbs lighter than the Z0.

synapse,

do you think your DP with an E-cutout welded in at the end will clear the underbody?

The tunnel on our cars aren't super wide, so it may, but would be very tight.
