I have a 2010 SHO. Can someone explain the exhaust system to me. I'm basically looking for what the components are from turbo back. I keep hearing "3rd cat" when reading these threads. I had no idea there were 3 cats!! :idea:
This should help. The 3rd cat is before the middle piece that looks like a small muffler (resonator) and after the flanges.
