Exhaust question
I just bought a 2005 convertible with Z51 package. Embossed on the tips of the exhaust pipes is "GCS." The mufflers are embossed with "GM Performance." Does anyone know if this is the stock system?

From what I can tell, it's just a little louder than a stock Vette. It looks to be stainless steel. The mufflers are quite large - like a typical muffler on any car. Depending on what you want, I think I'd want a little more open/louder but not obnoxious.

Me too. Perfect with top down. Can still hear radio or conversation at 70 mph. The Borla Stingers I had previously had an awesome sound under acceleration, but I could not handle the drone at cruising speed. The Sports IMO are perfect on this car.
