The Corsa sounds absolutely amazing IMO, it sounds much more aggressive than stock. I'll be posting a clip of mine on youtube soon. as well as a dyno run and track run.
I will be getting my camaro in around the first of next month. Do you like the Corsa exhaust that you ordered from GMPP? I am thinking about it, but I'm not sure on the sound. Does it sound much more agressive than stock?
