Product Reviews

I am very happy with the way this axel back sounds and the 4" tips looks great!

the fit and ease of these mufflers are only surpassed by the assume sound and I know they add hp thanks Steeda

Install took a little longer than expected, and had to have a friend to help, but it was definitely worth the work! Beautiful, deep, smooth sound from these axle-backs, but not irritatingly loud. Install on the left side was a bit tougher than the right, but after about 2 hours we had them on and lined up. Quality and finish is perfect. You will NOT be disappointed!
