Exhaust performance.

[LT.]

As some of you may know I have a thing for performance. I really like messing with engines and I am really into numbers, horse power, torque, and trying to make engines as efficient as possible. Well, anyways, tonight I was working on trying to see who makes the best flowing muffler, best sounding muffler, what size tubing to use and generally wasting time here at work. I found this thread in another forum and thought someone else may think like I do. Anyways here it is.
