So the nostalgia of having a car that sounds like a demon straight out of hell has worn off and the Flowmaster 40s have to go. I'm not looking to make a huge step down in sound but need some suggestions for mufflers that will still let that big block sing without vibrating my teeth out with drone at 2500 rpm. Suggestions?
