So im New to the cobalt scene i want to get a cat back that sounds good and perfoms well but dont want to spend an arm and leg for it....... so if anyone has some suggestions on which one and where to get it im open......



thanks ahead of time

 

Searching = Your best friend!

This really has been asked ALOT.

I will say GMPP is a great product at a great price.

But really, search.

 

beat me to it...

 

welcome ! and searching can be your best friend on here some days. not flaming ya because your brand new. but dont get a 3in exhaust unless you plan on some major mods. stick with gmpp or a decent sounding 2.5in.

 

dont get gmpp, i mean IMO its a waste of money its a 2.25 exhaust, get a nice 2.50 exhaust.

 

Megan!!!!!

 

megan is pretty cheap (if u can get one, good luck) but me personally dont like the fart can style

 

megan is nice i have one. but with the ss/sc bumper it hides a lot of it so you dont really see the whole fart can look of it. but mine on the other hand looks like one till i start it up

 

Quality = ARK

 

Dyno proven 12 hp = Waste??

 

magnaflow ftw!

 

always comes up. ONE person got 12 hp. that proves nothing. proof is repeatable, not some weird one time thing.

 

The GMPP CAN get 12 but its not a set 12.. Megan has a good cat back system from what i have heard and its the one im looking at

 

I agree, but people say it is a waste when I see no proof at all of a car not getting a gain out it. That is unless someone can show me a dyno where they were stock, then put the exhaust on and didnt gain anything?

 

I found that the the GMPP sounds the best, I also noticed a gain in power over the stock exhaust, I was really impressed, wasnt expecting any noticable difference it may be 2.24" but its absoluatly stright through muffler, if you wopuld even call it that looks more like a resonator, excellent flow! Definatly feel it in the butt dyno!

I researched a long time for a cat back system and went with the GMPP in the end, and I am very happy with it

 

If your only putting a cat back on and not change the stock downpipe , the 2.25-2.5-2.75'' arguments are irelivent . That 02 sensor crush point is going to restrict you in any case .

 

GMPP is only 2.25" diameter which is the only draw back. The corsa, IMO, sounds the same as the GMPP but it is 2.5" diameter.
