I'm going to be putting on an exhaust system here soon and I want to know what system would give me great sound.

 

What model cobalt and what engine?

 

I have magnaflow on my lsj and i think it sounds great. Ive heard that zzp has a nice lsj catback also.

 

If supercharged or n/a i have to recommend full zzp exhaust 2.5". go with a resonator and cat. anything bigger is not needed. other options are corsa but good luck finding one.

if lnf really most systems sound great haha but for supercharged most exhausts are really raspy.
