Benjamin E. ★★★★★

Swapped out my old muffler for this XL series and the difference in cabin drone is night and day. The oval shape fit perfectly in the stock hanger location, and the perforated core really does a good job smoothing out the exhaust note.

George T. ★★★★★

The perforated tubing and baffle design really tamed the resonance I was getting from my old setup. Exhaust flow feels much smoother now, and the oval shape fit perfectly in the tight space under my truck.

Thomas ★★★★★

Bolted this on last weekend and the perforated tubing really opens up the flow, throttle response feels sharper than stock. No drone on the highway either, which surprised me for a multi-chamber design at this price.
