I took my stock mufflers off while I was waiting for my Pype Bombs to be shipped. It's pretty loud, sounds good, but looks bad with no tips. The sound is just about identical to the Pype Bombs. Fair warning though...The tips of the midpipe bounce around really bad with no axleback/stock mufflers on there, so be careful going over large bumps and railroad tracks. The sound of exhaust pipes smacking your rear end isn't a nice sound. Good luck.
