+1 for headers and stock mufflers.

I've got that with hi-flow cats and the fuse pulled. I think it's basically perfect, though I would not mind a little more volume at idle and light acceleration. Nothing crazy, just a hair more would be perfect for me. The sound quality is great though, wouldn't change that for anything. Way better than all the Flowmaster Mustangs out there or even the muffler delete Mopars (most common ones around here).
