This new bolt-on XDR Off-Road® Competition exhaust system is for the 2016-2018 Polaris RZR XP Turbo and XP 4 Turbo. Does not include the Turbo S models.

Features include 409S stainless steel construction, a 2.25-inch mandrel-bent inlet tube flowing into the XDR Off-Road "straight-through" cross-flow Competition muffler providing a deep moderate 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.
