Great muffler

Comments On Jul 14, 2014:This muffler looks awesome, sounds excellent. Sound at idle is just a little bit louder than stock. When you get on it it is about 20-30% louder than stock. It sounds great. Good improvement gain. I installed this muffler, the fmf power bomb, and the fmf power management in about 45 minutes. Huge difference. Great power gains

Not as pictured

Comments On Sep 05, 2013:I Love my new pipe. Much lighter than the original AND sounds great with a little extra power. Mine came with a seperate rear mounting bracket NOT INTERGRATED ALL IN ONE LIKE THE PICTURE SHOWS. Apart from that very happy. It still fits perfect and looks great. I would of preferred it to look like the picture and had the rear mounting bracket as part of the system not a separate bracket. Shane
