There are a lot of riders on this forum old and new that would like to hear some sound clips for these types of mufflers; it's been said that on long runs they're a little easier on the ear, so if anyone has a sound clip or could make one, I'm sure it would be greatly appreciated by many. There are also some different styles of pipes: the S E Street Performance mufflers has a one piece slash down & a two piece with different tips, S & S SPO Ovals havea loud & quiet baffle and Rush has a 1.50" which are considered border line loud.
