Carter F. ★★★★★

The trapezoid shape is a genius design—it holds way more packing than I expected, so the exhaust note stays deep and throaty even after a few hard track days. Bolted right up to my 750 in about an hour, and the carbon muffler weight difference was noticeable the first time I swung a leg over. Defini

Joseph F. ★★★★★

The stainless steel construction feels solid and the carbon fiber tip looks great on my GSX-R. The fit was perfect and I noticed a solid power gain in the mid-range right away. It definitely has a deeper, more aggressive tone than stock without being obnoxiously loud.

Eli ★★★★★

The trapezoidal muffler body really lets the packing breathe—bike pulls harder mid-range and sounds properly aggressive without being obnoxious on the street. Carbon end cap looks trick against the stainless, and fitment on my 750 was dead-on.
