HMF Part Number: HMF-03569663
The Performance Series from HMF has been the staple of the brand since it’s origin. Whether on dirt or pavement, this exhaust system has the capability of generating an even increase in horse power and torque while distributing an aggressive deep sound.
The Polaris RZR® RS1 is available as a Dual Full System in the 4″ Performance Series. The Dual Full System picks up 4-5 horsepower 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.

Typically, fuel tuning is not required when installing an HMF Exhaust on this machine. However, other modifications to the machine may require the need for fuel tuning to ensure the machine runs properly, and there is no damage to the exhaust system.
