High-Performance Exhaust
This exhaust is shorter and lighter than my original muffler, and sits closer to the engine. My YFZ450R breathes easier with this exhaust, resulting in a significant power boost, especially at higher RPMs. And yeah, the carbon-fiber exhaust cap looks really cool.

Moderate Sound and Performance
Easy-to-install product with a bit more powerful sound at low RPMs. Expected it to sound more aggressive at higher RPMs. Pleased with its finish and look.

Sounds Perfect! Five Stars
I’m very pleased with the results. Installed this muffler without any problems. It fits exactly as described and provides a slight increase in top-end speed. And yes, it sounds really nice. Loud but not annoying. Just what I wanted!

Nice Product, Works As Described
What a nice exhaust! Very easy to install. Everybody can do it in less than 15 minutes. Looks stunning and gives a slight increase in performance. The sound is miraculous. It makes heads turn when I pass by.
