This exhaust system is engineered to deliver enhanced power output, improved throttle response, and a more distinctive exhaust note.

The PowerCore 2.1 system is a full-system exhaust, including a header, mid-pipe, and muffler. The header is designed with a 3-into-1 architecture to ensure optimal scavenging and maximum power gain.

The system's high-temperature ceramic coating not only looks great but also protects the exhaust from the harsh elements, ensuring long-lasting performance.

In summary, the FMF Racing 20137 PowerCore 2.1 Exhaust System is an excellent choice for Yamaha YZ250 riders seeking increased power, improved throttle response, and a more distinctive exhaust note.
