Customer Reviews (4.4 / 5 · 5 reviews)

Lily Q. ★★★★★

The mid-range pull on my 500 EXC-F is noticeably stronger now, and it feels like it added power everywhere in the rev range. Fitment was spot-on and the aluminum muffler keeps the weight down on tight single track.

Eli I. ★★★★★

Swapped the stock can for this stainless slip-on and the midrange pull is noticeably stronger on my 350. The aluminum muffler is lighter than it looks, and fitment was spot-on with no rejetting needed. Genuinely woke the bike up.

George ★★★★★

Bolted this on my 500 EXC-F and that 20% horsepower increase is no joke—the bike pulls much harder through the mid-range. The aluminum muffler also saved a bit of weight over the stock can.
