I'd look for an exhaust system in Stainless Steel. Plenty to choose from....RJC & Pypes come to mind. You might see a used Stainless Steel ATR 2 1/2" exhaust with Stainless Pit Bull Mufflers come available from time to time. These do pop up occasionally & are still one of the best systems .
Sounds like you're getting ready to start spending some money....(these cars are addictive), they don't call em "Black Crack" for nothing.
