When Polaris released the RZR XP 1000 it set the tone for the new generation of side by sides. This beast features a 999cc Displacement DOHC engine that rips through any terrain. When we got this into the HMF dyno room, we were foaming at the mouth to build an exhaust system that would elevate the power even higher. What emerged was the HMF Performance Dual Full exhaust system that picked up 4 horses at high RPM and 2lb torque at the wheels. The exhaust also picked up more power when we installed the HMF Quiet Cores, so not only do you get more power but the sound quality increases, with very low dB levels.
