This bolt-on XDR Competition exhaust system fits 2016-2021 Yamaha YXZ1000R and features 409S stainless steel construction, connects at the factory slip-fit connection and is firmly held in place using the factory rubber mounts. The 2.25-inch mandrel-bent inlet tube flows into the XDR "straight-through" Competition cross-flow muffler providing a deep moderate to aggressive sound level. The dual 2.25-inch mandrel-bent tailpipes are tucked up high within the rear fenders and are finished off with a pair of 3.50-inch brushed 304s stainless steel tips with black anodized aluminum end caps. The system comes with a custom black powder coated heat shield with a laser-cut XDR logo with venting cut in the shield showing everyone behind you why your YXZ1000R sounds so good. Includes all hardware and installation instructions necessary for a simple at home installation. Note: This system does not include a catalytic converter and therefore is not emissions compliant for on-road or trail use. For Competition use only.
