Check out our new XDR Off-Road Blow-off/Diverter Valve for all 2016-2019 Polaris RZR XP Turbo models. The factory internal diverter is known to warp and stick resulting in a loss of power. This kit replaces the factory diverter valve with an external blow-off valve which releases the excess boost pressure into the atmosphere creating that turbo swoosh sound that brings out our inner child. https://www.holley.com/products/off-road/xdr_off_road/xdr_accessories/parts/615904 | Flowmaster
