2009 G5 sedan S.E. sedan (base) 52,000KM
 

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.
