I believe with my income tax returns I will be upgrading my recently purchased 07 Cobalt SS/SC. I have selected the Injen cold air intake from turbotechracing.com and I want an exhaust system headers back that will really wake the car up in sound and performance. I'm open to all suggestions but I would like proof with your suggestion please.

Thank you,

I have the GM Performance Cat-back. I like the sound, and had my car dynoed with just a Fujita intake, and that exhaust and made 233whp and 200 tq.

wow thank you Bullet. that is for sure nice sounding and really good advice. I will probably be going with that set up. I was looking at a full Hahn headers dp and cat back and he claims 15-20 hp gains at maximum...im new to the tuner world so Idk about these cars that muchq

Hey, I've been looking and asking around about different exhausts for my car. anyone got any good ideas or tips?
It's a 2009 Ice Metallic Silver Cobalt SS Turbocharged.
I already got stage 2 turbo and a stage 2 clutch in it that took it from 260hp/260tq. to about 297hp/350istq.
I'll post pictures of my car in a bit.
