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.

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.
