"1 cut needs to be made directly infront of stock muffler_ easy install after that" posted by: Chad williamson on October 3, 2009

"This is the second or third Borla system I have had. They never fail to please, for me. Great performance, high quality, looks good, sounds great. It is never harsh, like some system can be, when they get a resonance at a certain engine speed, and that speed happens to be where you normally travel. This is smooth all the way through. Yet when you down-shift or accelerate hard, it has a nice deep, throaty growl." posted by: GordianKnot on December 9, 2008 view all 3 reviews
