Im lookin into gettin a full exhaust and downpipe soon, and i was just wondering what exhaust i should go with. id kinda like a 3". and my plan is to get the synapse DP. just lookin for some help. lol! thanks!

 

not too many catbacks to choose from now

hahn has a 3 incher, but the stocker flows very well to begin with.

I believe magnaflow has a part number for the 08/09 ss cobalt on their website, but not sure if you can buy it yet.

 

i was gonna probably go with a custon exhaust, no mufflers just straight pipe like on my srt-4

 

yea and i think a custom straight pipe w/o a muffler would be cheap.. and it would probably burble like the srt-4..

 

I have the synapse DP and am getting a prototype SLP installed end of the month. The aftermarket is always slow to let parts trickle out, but Hahn has a nice system out for the time being.

 

damn u wobblez get a custom 3in SS made. ******* flow master super 40 series. that is all. /end thread

 

do not get a fartmaster. sraight pipe on a turbo would be just right

 

I say wait for a little while until you have more options. That way you won't feel like a goof if you get something now and something you like more comes out.

 

How the hell is the stock exhaust not good enough?

 

Personally, I love the stock exhaust. There is no noise at cruising speed and has a decent sound when you really get on it...and it is not very restrictive for a stock exhaust...

 

i am doing a custom cat back

synapse dp
with 2.5 inch straight pipe

 

not restrictive my ass you dont think 2 cats is restrictive??? your smoking somethhing and our mufflers are huge the only reason our cars sound good and it would free up so much hp with a strait pipe and you would get such a faster spool time

 

My Wife is planning on getting me a custom exhaust setup done here soon. She called the muffler shop in town, the only one I've ever been to in all of my cars and they have 3" piping and it would cost something like $125 or some **** plus taxes. If the shop did it, would it be a smart idea to run straight pipe from the turbo back without a muffler or cats? Just dont wanna have a car that sounds like **** and drops power.

 

yeah our stock exhaust does sound good! but F the 2 cats... wtf is that?? im leaning tward the Hahn Exhast i think? or i might get a custom bent muffler man exhaust. but i want a muffler. im thinkin Greddy, they make sexy evo and subie exhausts.

 

I have a Hahn 3" polished SS exhaust. The resonator and muffler are full ID of pipe. The sound from outside is great, but almost stock from the inside. I am really enjoying this car. All I can say is "WOW - well done Chevrolet".

 

Awsome!! yeah im deff. leaning to getting the Hahn. i was listening to some sound clips of different exhausts on youtube and that was the one that sounded less ricey. lol! so well see.

 

get the hahn ill get a sound clip up for u here soon ull love it

 

A custom 3" exhaust would save me about $300 or so, so get that clip up so I can see if I wanna pay the extra $ for Hahn.

 

cut thet muffler off weld up a 4.5 tip and then get a high flow dp

 

WELL HOW IS THE STOCK EXHAUST GOOD?
ITS IN THE PIPING DUDE
3" IS WAY BETTER ON A TURBO,AIR FLOWS MORE FREELY WHICH MEANS MORE HP
ADD A DOWN PIPE AND YOUR SET

 

WORD!

 

Muffler shop exhaust is not going to be any better than stock EXCEPT for muffler choice. The TC comes with 2.5" mandrel bent as is. A press bent 3" pipe is smaller than 2.5" in the bends so it defeats the whole point. I know this because I used to run an exhaust shop. Mandrel bent is the way to go unless you like giving away money, in which case, you can give it to me......lol. I'll put it to good use!!

 

unless the shop can mandrel bend

 

so mandrel bent 3 in would be perfect? i want an angled exhaust lol because no one has it but is the stock tip 2.5?

Just get the DP, you don't need any thing else.
