HMF Muffler Honda TRX 400EX 99-14 Black Competition Full System Exhaust

HMF Muffler Honda TRX 400EX 99-14 Black Competition Full System Exhaust
Since the early garage days, HMF has been developing high-performance exhausts that increase horsepower and torque on ATVs, UTVs, and motorcycles. Our exhausts have a deep, aggressive sound that fattens up the overall tone of the machine, keeping higher frequency pulses down to a minimum. We manufacture various exhaust series that have a specific volume output to make us one of the most versatile off-road exhaust systems on the market.
Today, HMF is a leading worldwide supplier of performance exhausts for the Powersports Industry. Pushing the limits in our research and development is how we come up with new ways to solve the needs of off-road riders. HMF is on the front line of Powersports engineering to keep riders, like you, moving ahead towards the next adventure.
The Competition Series was designed and tested for sport ATVs. It features three inserts that affect the sound and power differently, giving you complete control over the type of power and sound you need, when you need it.
The Honda TRX 400EX is available as a full system in the Competition exhaust series. The Competition Series Full exhaust delivers a 1525% increase in horsepower and torque throughout the power curve. The mufflers are approximately 46 dB louder than the stock exhaust, but the Competition Inserts and HMF Quiet Core can reduce that by 26 dB.
