Customer Reviews (4.8 / 5 · 5 reviews)

Richard S. ★★★★★

Installed it over the weekend and the difference in low-end torque is noticeable on rocky trails. The welded construction feels solid, and the sound is aggressive without being obnoxious on the highway.

William J. ★★★★★

Had to cut out the old rusty system, and this bolted right up with no modifications needed. The sound is deep and throaty on the trail without being too loud on the highway, and I definitely felt a bit more low-end grunt crawling over rocks.

Isabella ★★★★★

The deep growl at idle is exactly what I wanted for trail runs, and the weight savings made it easier to feel the suspension. Installation took about an hour with basic tools, and it cleans up the underside nicely.
