i just wanna know which DP doesn't throw a code!!

 

ok guys

If your going for a tune

its best to do a catless DP because the Cat cloggs.

I didnt do it for the sound. I did it for safety.

I had no idea it would sound like it did when i bought it

I paid 280 for my DP from CIA

the Stock DP is a big restriction on the car.

aftermarket parts for the LNF do no good bc of the learn down and only if u get a tune. the power of the DP and other parts will be released.

 

CIA or Hahn

 

All of them that come with a drilled out anti-fouler.

Get the cheapest stainless steel one. A DP is a DP, and get a catless one, it is not loud without one, or I wouldn't have it.

 

So has ANYONE dynoed a stock downpipe vs. a catted/uncatted downpipe?

It seems that too many people are trying to make the car sound cool, and not really doing anything with gains and/or track times....

 

10-20 Hp With Tune!

 

pm me with where you live in nj maybe we could meet and you could here my car with stock catback and CIA'S dp.... i love it...

 

Get the hahn DP, ITS WORKS GOOD

 

From the comparison of the 2 they are nearly identical...even price wise TTR sells Hahns for only 25 dollars more than CIA. I guess my biggest question is, which is better quality? Maybe vendors can chime in on this...both flow the same, both throw no codes, both are nearly same price, both are mandrel stainless, but what is best quality.

Side note...CIA does offer a cheaper aluminum one as well, and I think they offer a cutout option too. But Hahn offers modpipe.

 

Since you asked for the vendors to jump in.

We build our down-pipe with an interlock flex coupler. I have no idea what the other guy uses.

We do not offer a MOD pipe because it is not neccessary. We designed our pipe to allow members to order the cut-out option with either a hi-flow converter or cat delete. No swapping parts is required so we can offer much more for much less cost to the owner.

Qualit-wise?? We consider ourselves the best in the industry. Though we do believe Hahn offers beautiful finish work.

 

Yeh I know you guys are quality Dan. Notice the quickness of Dan to back his product up, that kind of shows that not only CIA has quality but also pride in product. IMO CIA DP FTMFW!!!

 

im either going CIA or ZZP for my downpipe. Im sure both are very similair.

Personally I love Dejon powerhouse and would have loved to do a full Dejon setup like people do a full Hahn setup but without that angled O2 bung...i just cant rock that.

 

Synapse made an extra 15whp with their downpipe WITHOUT A TUNE. So much for Learn down. Plus it sounds like Sex.

I believe they unlocked it. I believe all of them can unlock the ecu with out messing with the tables. Basically take the "learn down" out of the picture then dyno. I could be wrong on this, knowledgeable members feel free to chime in.

 

Just bought my downpipe and put it on sounds soo good (also have muffler delete, kinda loud) but paid $199 for the ADM downpipe (great quality) however it does throw a code but that all gets fixed when you get tuned! provided you get a tune that can turn off the o2 sensor.


if your looking at zzp look at adm too nice pipe! no homo

most ss/tcs dyno at 240 something you can gain up to 260/260 is where the learndown stops you.

 

I have ZZP's downpipe... Paid 204 SHIPPED TO MY HOUSE!

Fit perfect the first time... angled bung for no COT codes... And sounds amazing!

 

like i was told when i bought my dp, the name doesnt make more horsepower 3 inch cattless downpipes do.

 

That would be how I look at it too....

You can ALL search my posts... I am not a Huge ZZP fan either!

 

You can't just "unlock" that feature as it is not technically a setting. PM Vince from Trifecta and he'll explain why I'm sure. He knows more about the ECUs on this car than...pretty much anyone on this site..I'll try to PM you with a big long post he had about it in the solstice forums I believe.

In short: the computer just targets a certain airflow...not HP or TQ or anything...airflow. if your stock components can't reach that airflow, then aftermarket bolt ons will help. if you're already making the factory air-flow .

Edit: not Solstice forums.

I wish ALL LNF owners would listen to Vince. HE KNOWS LNFs.

 

No you cannot just "delete" the learn down....

 

I went ahead and got the Hahn catted ModPipe from Turbo Tech Racing. I have a few PM's out to people because I am not sure I should install it before or after the GM Upgrade.

Will the upgrade learn that there is a DP on the car or will the DP be taken into account when he tune is installed?

Wonder when the optimum time is?

 

Nope becausethe desired airloads and max airload torque is all we can control in Hp tuners. We cannot see the tables that the GM stage tune changes to increase the boost pressure from 15lbs to 21lbs. Hopefully they will unlock more tables soon. If it wern't for the cam tables I would be very bored right now.

Once the tune is done the "learn-down" feature will be disabled.
