HMF RZR Turbo Slip-On Exhaust System
Experience unmatched power, performance, and sound with the HMF RZR Turbo Slip-On Exhaust, engineered exclusively for the Polaris RZR XP Turbo EPS. This high-performance exhaust system is available in both the Performance and Titan Series, delivering a proven increase of up to 5.5 horsepower and 3 lb-ft of torque.

Built from durable materials to withstand extreme off-road conditions, the HMF Slip-On system combines precision engineering with a sleek, performance-driven design. The stainless-steel construction resists corrosion and heat damage, while the easily serviceable components ensure long-term reliability. Whether you’re conquering dunes or tackling rocky trails, this exhaust delivers a noticeable improvement in throttle response, turbo spool, and overall driving experience.
