Yoshimura RS-2 Enduro Stainless Full Exhaust with Aluminum Muffler | Honda CRF250F | USFS Spark Arrester Installed

The Yoshimura RS-2 Enduro Stainless Full Exhaust System is a complete header-back exhaust for the Honda CRF250F, featuring a stainless steel header, a parallelogram-shape aluminum RS-2 muffler with a carbon fiber end cap, a straight single-core baffle, and a spark arrester installed from the factory — so it is trail-ready in all 50 states straight out of the box.

That last point is the reason to choose the Enduro Series over a race system. A CRF250F is a trail bike, and trail bikes ride on public land where an approved spark arrester is not optional. Most performance exhausts ship without one and require a separate insert purchase; this system arrives compliant, and it is still low-volume-insert capable if you want to quieten it further.

The parallelogram muffler shape maximizes internal volume within the space available beside the subframe, which is what lets the straight single-core baffle flow freely while keeping sound in check. The system carries Yoshimura's factory race development directly across — the same work that lowers sound levels and centralizes mass on the race bikes.
