I was looking for the crisp tink/tink sound at idle with my 383 stroker and searched the internet and youtube for a few months before deciding on something..This shop here Kenny's Muffler has some excellent youtube videos of mufflers done on cars with great sound and you can also seach youtube for the car and mufflers, there is always something for everyone there..

I have Long tube headers into X-Pipe with FlowMaster Super 44's that dump out behind the axles...Great sound and not too loud cruising..
