HMF Exhaust Grizzly 700
Adding an HMF exhaust to the big-bore, single cylinder Yamaha Grizzly makes this machine a true Grizzly bear! Compared to the extremely restrictive stock silencer all HMF systems improve power, torque, throttle response, and of course, sound. Available in slip-on or full system configurations, HMF exhausts for the Grizzly 700 are available in the Performance and Titan series.
Performance Series
With a lightweight, 16” aluminum shell, numerous customization options, and the signature HMF Performance core, the Performance series exhaust matches the Grizzly’s aggressive look with equal style and sound.
Titan Series
The complete stainless steel 16” shell of the Titan series ensures maximum durability, and long-lasting good looks with no compromise in performance. Available in both XL (loud) and QS (quiet) owners can choose to let their Grizzly roar with the XL version, or keep it tame (relatively) with the QS.
Performance Stats: +4-5 hp & +3-4 ft-lbs.

Stock: 85 dB
