COVID-19 Update

As of the close of business Monday March 23rd, 2020, HMF Racing will be temporarily closing manufacturing and operations until May 1st as mandated by the State of Ohio to help slow the spread of the COVID-19 virus. We hope to resume normal work May 2nd, 2020. This is to protect the health and safety of all HMF staff and their families.

All orders that are currently in progress will be put on hold until operations resume. In Stock items are available to ship with negligible delays. New orders may still be placed on our website. Orders placed online will be charged and invoiced the next morning in order to reserve a place in the production queue. Delays in production in addition to the listed production time are possible depending on the volume of orders placed during this closure period.

From the HMF family to you:
Stay safe, stay healthy, and we look forward to helping you with your exhaust and equipment needs in the very near future.

Polaris® RZR Pro XP®

The Polaris RZR PRO XP® exhaust systems are available as Dual Slip Ons in the Performance Series, Dual Full Turbo-Back in the Performance and Titan Series, and a Single Full Turbo-Back Big Core in the Titan SS Series.

All the dual systems use 16” silencers.  The Slip-On systems retain the original downpipe and turbo heat shields.  The Full Turbo-Back Systems will still retain the original turbo heatshields but replace all the exhaust components after the turbo.  All dual systems include a powder coated aluminum license plate bracket. 

Performance Series
Dual Slip-On 
The 4” diameter aluminum silencers replace the stock silencer and are significantly lighter.  

Dual Full Turbo-Back 
The 4” diameter aluminum silencers and stainless steel downpipe replace the entire exhaust system from the turbo back.  The downpipe includes a flex joint and custom laser-cut heatshield that mounts to the downpipe.

Titan Series
Dual Full Turbo-Back
The 5” diameter stainless steel silencers and stainless steel downpipe replace the entire exhaust system from the turbo back.  The downpipe includes a flex joint and custom laser-cut heatshield that mounts to the downpipe.  Available in both the Loud (XL) and Quiet (QS) options. 

Titan-SS Series
Single Big Core Full Turbo-Back 
The single 5” stainless steel silencer and unrestricted 2.5” downpipe was designed and built for serious racing and enthusiasts alike.  The silencer uses a 2.5” core to match the downpipe and minimizes back pressure on the turbo and helps to keep the turbo spooled for the best possible throttle response.

Exhaust Weights (weight difference to stock): 
Performance Dual Slip On: 15.05 lbs (-4.30 lbs compared to a stock silencer)
Performance Dual Turbo Back: 21.20 lbs (-5.05 lbs)

Titan QS (Quiet) Dual Turbo Back: 27.20 lbs (+0.95 lbs)
