Hey i currently own a 2006 cobalt ss/sc with a stage 3 bolt on kit no other mods, just wondering what exhaust sounds the best with no mods other then the stage 3 and a whole cat back system.
Thanks,

Cody

 

Corsa Sport IMO. I had it and had people following me to ask what it was. Its loud though at WOT, but low and growly when cruising under 3K.

 

Thank you

 

I have a lot of experience with these. The touring and sport are very similar at low cruise rpms, but when you romp on it, the sport sound much more aggressive. Also, no cabin drone :P
Con: Cost. They don't give these away. They put a lot of R&D into these systems and you pay for that. But... once you compare the sound to the GMPP exhaust you'll agree its money well spent.
