David ★★★★★

The carbon muffler looks incredible on the bike and sounds properly aggressive without being obnoxious on the street. I’ve put about 500 miles on it and the mid-range pull feels noticeably stronger than the stock setup.

William G. ★★★★★

Installation was straightforward, and the carbon muffler looks incredible against the bike's lines. I noticed a definite improvement in throttle response through the mid-range, and the sound is deep without being obnoxious. Really happy with how it transformed the ride.

Emily B. ★★★★★

The AT2 full system really woke up the mid-range on my Ninja 650, and the carbon muffler has a sharp, deep note without being obnoxiously loud. Fitment was spot-on with the included hardware, and the weight savings are noticeable when flicking through corners.
