Polaris RZR XP 1000 HMF Performance Dual Exhaust System

Free Shipping!

The Polaris RZR XP 1000 HMF Dual Full System is available in the 4" Performance Series. The Dual Full System picks up 4-5 horse power at high RPMs and 2lb of torque at the wheels. The exhaust system also picked up more power when we installed the HMF Quiet Cores.  Additionally, the aluminum shells and stainless head pipe weigh substantially less than stock.

Note: This system will use a wideband oxygen sensor that has 18MM threads and we absolutely recommend using the Dobeck AFR + Gen 4 fuel controller.
