Yoshimura RS-2 Stainless Full Exhaust with Aluminum Muffler | Honda CRF150R / CRF150RB 2007-2026

The Yoshimura RS-2 Stainless Full Exhaust System is a complete header-back exhaust for the 2007-2026 Honda CRF150R and CRF150RB, built with a stainless steel header feeding a diamond-shape aluminum RS-2 muffler with a stainless end cap, and it accepts both spark arresters and sound inserts.

The CRF150R has been the benchmark four-stroke minicross bike for the better part of two decades, and it is raced hard by riders whose next step is a full-size machine. Its stock exhaust is heavy and restricted, and on a 150cc four-stroke the exhaust carries a disproportionate share of the available tuning.

The RS-2's pyramidal canister increases internal packing volume over a round muffler of the same footprint, which is what lets it add power and sharpen delivery while running quieter than the pipe it replaces — the combination that matters at sound-tested amateur nationals.
