probably dont need a performance muffler... i just want a manly low rumble from the exhaust... My father in-law has a 70 mach 1 and has turbo mufflers with headdman headders just not the low manly rumble that im looking for... they sound nice dont get me wrong but not what im looking for...
If you don't need a performance muffler, you have a wide open field. I have Flowmaster 50s, x-pipe and tri-ys. I think I'm giving up some HP, but everyone likes the sound. No drone. As I said earlier, next time I'll get something that flows a bit better.
