Aurora C. ★★★★★

The welds on this Works Finish system are clean and the carbon muffler looks incredible. It bolted right up to my MT-07 without any fuss and the overall build quality is clearly top-tier. The sound is exactly what I was hoping for, deep and aggressive without being obnoxious on longer rides.

Nicholas ★★★★★

The full system bolted on without any hassle, and the carbon muffler looks incredible against the bike. The sound is deep and aggressive without being obnoxious, really wakes up the mid-range. Definitely feels like a proper race part.
