Exhaust Series We Recommend:
The Swamp is great for it's large mechanical core that directs and controls sound pulses to keep sound levels approximately 1-2 dB over stock.
Other Exhaust Series Available:
Penland Pro Series
Swamp XL Series
|The HMF Performance Series has a specially designed, unrestricted core that allows the exhaust to increase power evenly throughout the entire power curve. It also features the signature HMF sound with industry-leading end cap and color options, giving you a completely custom look.
|Backed by ATV legend Mike Penland, the Penland Series was developed for serious off road racers and trail riders striving to achieve more low end torque. The Penland features the same core as the Performance Series, but features the removable TRM that allows quads to hook-up in rough conditions.
|The younger brother of the Swamp Series, the Swamp XL Series (extra loud) offers anywhere between 1-2 more horse power than the standard Swamp Series. What makes the Swamp XL different than the Swamp Series is the non-restrictive core that produces very high dB sound levels.
Each HMF Exhaust:
Whenever you add an after-market exhaust system to your machine, tuning your carburetor is, in most cases, an absolute necessity. The proper jets and EFI settings are extremely important for the performance and lifespan of your machine. Tuning Kits
are available to ensure your machine runs at it's top performance and your HMF Warranty remains valid.
