Yamaha’s Rhino 660 offers an abundance of features that has put it at the top of the UTV ranks. The 660cc, liquid-/oil-cooled, four-stroke, five-valve engine responds perfectly to the HMF Dual Performance System. On the dyno, we noticed a 14% increase in horse power across the power curve with an insane amount of torque. This allowed the Yamaha Rhino 660 to travel through terrain it never used to be able to conquer.

HMF Performance Series:
Setting the standard for power and value, the HMF Performance Series has been tested for over a decade with endless championships. The specially designed, unrestricted core allows the exhaust to increase power evenly throughout the entire power curve. The Performance Series has the signature HMF sound with industry-leading end cap and color options, giving you a completely custom look and sound.

Swamp Series: Don’t let the name fool you, the Swamp Series is more than a deep-mudding machine. It is the original in setting new standards for horse power, sound, and durability. What makes the Swamp Series so unique is the 5-inch diameter shell. This gives the exhaust more internal volume which, in turn, produces larger horse power gains. The large mechanical core directs and controls sound pulses to keep sound levels approximately 1-2 dB over stock. It’s shell is made of 304 stainless steel and the inlet is TIG-welded shut for a water tight seal.

Swamp XL Series: The younger brother of the Swamp Series, the Swamp XL (extra loud) offers slightly more horse power than the standard Swamp Series. What makes this exhaust different is the non-restrictive core. Since there is nothing inside the core controlling sound pulses, the exhaust is louder than ever. Strap this to your machine and we guarantee you will be heard by everyone.
