i have heard that you can interchange the cat back part of exhausts from any model to any model like if i bought a cat back made for a 2.0 supercharged i could put it on the 2.4 ecotec model is there any truth to this???

 

u can do the full exhaust

 

on turbotech racing the magnoflow exhuast for the 2.2/2.4 is more expensive then the 2.0. i dont get why that is if they are both the same

 

thanks yall trying to gain info so i can start modding the car

 

get the gmpp cat-back.
it isnt cheap but its bolt on and not ricey at all.
slight gain. dont thinkin your gonna haul major ***** from it thought lol.

 

ya any type of exhaust for a cobalt can fit lol

 

thanks for all the input yall

 

Different diameter piping?
