HMF Racing Muffler Yamaha Grizzly/Bruin/Wolverine 300/350 04-11 Performance Slip On Exhaust

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 Performance Series exhaust has been the staple of the brand since the origin. Whether on dirt or pavement, this exhaust system has the capability of generating an even increase in horsepower and torque while distributing that signature HMF tone.
The Yamaha Bruin 350 is available as a Slip-On System in the Performance Series. The Performance Series Slip-On System picks up roughly 10-15% more horsepower and torque throughout the power curve. The HMF system weighs substantially less than the stock muffler, so you'll see an overall weight drop. The Performance exhaust will increase sound levels approximately 4-6 decibels above the stock muffler, but the HMF Quiet Core insert can lower that 2-4dB.
