Daniel S. ★★★★★

The pyramidal shape of the muffler really stands out once it's mounted—looks aggressive but sits clean. It fired right up on the first try and the throttle response feels noticeably sharper than stock.

Kevin X. ★★★★★

I was a little worried about fitment on my ‘15 YFZ, but it bolted right up with no issues. The aluminum muffler saves noticeable weight over stock, and the power delivery feels much smoother across the mid-range.

Thomas ★★★★★

The pyramidal muffler shape fits the bike's lines perfectly, and the stainless steel construction feels solid. Throttle response is noticeably sharper from idle to wide open.
