I was just thinking how these kind of threads are pretty much misleading for the new comer. I bet a lot of people watch these clips of cammed out 500hp cars with 3 inch exhaust and say "oh man i'm gonna buy THAT muffler because it sounds sick".
I honestly would love to take a 500hp Mustang and put some Honda fart pipe mufflers on it...just to show that it doesn't really matter what muffler you run on an engine that powerful, it's going to sound mean no matter what.
