Customer Reviews (4.8 / 5 · 5 reviews)

Robert T. ★★★★★

Installed this on my R-77 and the carbon fiber tip looks fantastic, really cleans up the look. The 1.500" diameter fit perfectly with no extra shims needed, and the sound dropped to a manageable level without losing tone.

Harper ★★★★★

Swapped this into my R-77 and the fit was spot-on—no wrestling with misaligned holes. The carbon end cap looks sharp, but what I really appreciate is the noticeable drop in bark at cruising RPM.

Charlotte H. ★★★★★

I needed a bit more restriction for track days, and these inserts slid right into the R-77s without any hassle. The carbon fiber tip matches the muffler perfectly and feels solid. Definitely toned down the bark without killing the growl.
