You just got back from a ride and you heard a quad that sounded like a friggin’ HARLEY! And he had all the power in the world. Now, you want in on the secret?
HMF Exhaust Systems are the most popular aftermarket pipes on the market. When you HEAR an ATV go by and it really gets your attention, chances are, there’s an HMF under the fender.
Loaded with power, the HMF is ideal for competitive racing and can be modified to ride in any condition. HMF Exhaust Systems even meet the USFS criteria for national forest and public land us. The exclusive two-piece billet end-cap allows for on-the-fly insertion of their Quiet-Core and USFS approved spark arrester. HMFs are designed with larger diameter stepped head pipes and a 2” open-flow non-restrictive core to produce MAXIMUM HORSEPOWER and TORQUE throughout the entire power-band. The HMF Utility Series is packed with Silent Sport brand ceramic pillow packaging which gives HMF mufflers that distinct, deep, rich tone and carries a five-year warranty.
Each HMF Utility Series Exhaust System is hand-crafter using 304 stainless steel headers, inlets, and rivets, mild steel cores, solid construction T6061 aluminum canisters and brackets. All of which are perfectly fit to make the highest quality, high performance ATV exhaust systems on the market today.
In other words…THESE HMF PIPES ARE THE BOMB!!!
