Lucy ★★★★★

Installed these on my 2023 bike and the satin stainless finish matches the frame perfectly. The sound is aggressive but not obnoxious, and I noticed a solid throttle response improvement. Very happy with how they transformed the ride.

Adam ★★★★★

The satin stainless finish looks even better in person than in the photos, and the dual mufflers give the bike a deep, aggressive tone that's hard to stop revving. Fitment on my 2021 was bolt-on perfect with no tweaking needed.

Robert Z. ★★★★★

Installed these on my bike and the satin stainless finish looks even better in person, the build quality is clearly top-notch. The sound is deep and aggressive without being obnoxious on the highway, exactly what I was hoping for.
