I loved my Corsa Xtreme on mine. All it had was a CAI intake and the Corsa Cat back and a SCT tune to get rid of AFM and it sounded amazing an no drone at all. Great combo.

I am selling my Corsa Xtreme Cat Back Exhaust. Just replaced my Camaro with a 2012 Grand Sport.

Ya...it truely is imo the best sounding exhaust for the Camaros. My tuner says the Corsa with longtubes is the best sounding combo on the market.

Proper way; get rid of that funky L99 resonator, headers and a tune.
So many wreck a prefectly good exhaust system with a cat back.....waste of money.
Good luck.

Respectfully disagree with cat back being a waste. I'm in NC and there is no way I could pass state inspections by deleting cats. My Borla cat back made a huge improvement on sound quality and provides better flow but is still emissions legal. I also didn't want the car to be ridiculously loud. Best $1,000 I've spent.

Long tube headers with or without high flow cats will give you the best power and sound improvements.
