i might be getting a gmpp cat back exhaust but i dunno if i wants to get performance or touring. would there be any gains in HP with the cat back. if i get the gmpp exhaust would i get a new catalytic converter too.? also im thinking about getting gmpp intake too. If i had gmpp exhaust and gmpp intake, would i have any gains in HP? would i see a differemce in throttle response?...................................

Thanks,

 

Anybody?????

 

my advice, post in the regular cobalt forums. g5's and cobalt are the same freakin car on difference is badging, and the ss's are totally differrent. but all base model cobalts and g5's are the same.
