The Yoshimura RS-2 Stainless Full Exhaust System is a complete header-back exhaust built with a stainless steel header feeding a diamond-shape carbon fiber RS-2 muffler with a stainless steel end cap, and it accepts both spark arresters and sound inserts.
The RS-2 is Yoshimura's value-oriented off-road canister, and the engineering that defines it is the pyramidal sleeve. It carries a larger core and more packing volume than a round muffler of the same footprint, which lets it add power and sharpen throttle response while actually running quieter than the pipe it replaces.
The carbon sleeve on this version saves weight over the aluminium equivalent, and the diamond section adds durability where an off-road muffler takes rock strikes and tip-over damage.
The specification above is confirmed, but the motorcycle application for this part number is still being verified. Contact us with your make, model and year and we will confirm fitment before you order. Fit an approved spark arrester insert before riding on US Forest Service or BLM land.
