Hi everyone,

I need an advice, I own a Cobalt SS/TC 08 with a GM Stage 1, I want to change my exhaust to have a good sound (not so loud because the cops are a little picky here!) and I want also to have a gain of power with that. I already have a K&N SRI. I check on Modern Performance and I found a pretty nice kit ( Exhaust Systems - MPx 3inch Downpipe & Catback Exhaust Package 08-10 Cobalt SS ), but my friend said that a Catback exhaust didn't give u any more power until you don't change for a headers. So, do I really need to get a headers for more power, does it give me some check engine problem with the catalytic system? Where can I find good quality of headers on internet?

Thanks a lot guys.

 

Your friend is a ricer. SS/TCs don't have headers. They have a twin scroll exhaust manifold and the only reason to change it would be to accomodate a non-twinscroll designed turbo setup.

 

But seriously, I'm an lsj and I don't even have headers

 

Lmao

 

Wow, quite a few "make me want to punch small children" threads lately.

 

I think he's joking

 

 

cobalt =/= corvette

 

Instead of a header, I think the term you want is "down pipe" this is where the cat is and one of the points of exhaust restriction. Several companies make them, there's a down pipe thread if you do a search. Swapping this out will change the sound of your care and change the performance. To really take advantage of the performance change, you'd want to get your car "tuned". Again, check the forums for information on tuning. Trifecta and HP tuners are good search terms.

 

Ok thank you for your fast reply, I want to keep my GM Stage 1 to keep my warranty clean. I think that I'll buy this catback from Modern Performance.

 

 

 

hahaha

 

Friend shouldn't be around cars or learn what he's talking about and you own an LNF and know nothin about turbo vehicles ...why dude why...not trying to down talk but seriously wth man

 

Since the guy is from Quebec there is a good chance he is not talking in his native tongue and is doing a lot better than any of you would talking in French. Give him a break.

 

Thank you bro, I try to speak the best that I can in english and I'm not a master in car mechanics!

 

I don't know why everyone thinks this is so hilarious, there are plenty of cars that have headers that are often changed for a new exhaust...

 

i have four headers that connects into one to the downpiper

 

No cobalt has headers. That's why haha

 

i would think every cobalt minus the SS/TC would have a header... seeing how theirs doesnt connect to a turbo or anything..

 

Yeah ..... some have a header ...... but very few have headerS. The ones with headers look like this .....

 

u need to get a catless downpipe not a catback.

 

I didn't realize the English/ French speaking problem. For that I take back my statements about headers lol
