Yamaha® Bruin 350

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 horse power 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. 

Exhaust Fits: 
(04-06) Bruin 350, 2WD, 4WD
(06-09) Wolverine 350, 2WD
(07-11) Grizzly 350
