Check out our BMP Big Mo full exhaust for the Polaris RZR XP Pro.

Huge gains on pump fuel while increasing the longevity of turbos and exhaust valves due to lower EGT.

The 3" tubing also allows for a quicker turbo spool and works more efficiently versus stock as the boost pressure increases.

Fit specifically for the XP Pro.
