High-Performance Exhaust
FMF Racing® - Factory 4.1 RCT™ Slip-On Muffler
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.

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.
