HMF Part Number: HMF-041293606071
The Performance Series from HMF has been the staple of the brand since it’s origin. Whether on dirt or pavement, this exhaust system has the capability of generating an even increase in horse power and torque while distributing an aggressive deep sound.
The Yamaha Grizzly 550/700 HMF Slip-On is available in the Performance and picks up 10-15% more horse power and torque throughout the power curve, and remains substantially less that the stock exhaust. The Performance exhausts are typically 4-6 decibels above the stock and all series of exhausts can use the HMF Quiet Core insert for a 2-4dB drop in sound.
Fuel Tuning is absolutely required when installing an HMF Exhaust on this machine. Failure to tune the engine can cause excessive damage to the exhaust system and engine, while voiding the warranty on your exhaust and possibly on your machine. (check with local dealer).
