Customer Reviews (4.6 / 5 · 5 reviews)

Richard V. ★★★★★

Weight is noticeably less than stock, and the stainless muffler gives it a clean, modern look. Installation was straightforward, with all hardware lining up perfectly on my SP2.

Riley R. ★★★★★

The sound is deep and aggressive without being obnoxious on the highway. I was worried about fitment but the hangers lined up perfectly with the stock mounting points. Gives my CBR exactly the attitude it deserves.

Samuel ★★★★★

The install took maybe 20 minutes since it’s just a slip-on, and the stainless muffler casing feels solid without adding noticeable weight. I’m honestly surprised how much cleaner the throttle response feels at low RPMs compared to stock, even if it’s not the loudest option out there.
