The Muzzy full exhaust for the RZR XP-900 is 2 into 1 into 2 system featuring large diameter stepped head pipes for the largest power increases throughout the power band. Longer dual oval aluminum muffler canisters provide an agressive sound without excessive decibel levels. What truly sets this system apart from the rest is the new Muzzler™ midsection that reduces sound levels significantly without horsepower robbing restriction of exhaust flow. The muffler canisters feature the Modular Endcap System with spark arrestor screen and quiet core and are available in polished, brushed or black coated finishes. Muzzys recommends the Digi-Tune Pro Fuel Tuner when purchasing the full exhaust.
