MBRP Yamaha Raptor / Grizzly Sport Muffler Exhaust

Fits: Yamaha YFM660 RAPTOR 2001-2005 / YFM660F GRIZZLY 2003-2004

At the heart of the system is a unique muffler design that uses a series of internal tubes and resonant expansion chambers to capture and cancel unwanted sound waves, leaving a crisp, but quiet exhaust note that exceeds today’s sound level requirements regardless of where you ride. The fully welded design and no packing materials means zero maintenance. Generally, sound levels run in the mid to high 70-80 DBA range depending on the model.

• Includes a slip-on tube that connects the silencer to the factory head pipe, a clamp, hanger, all necessary hardware to complete the install and a free spring puller to make the job a little easier
• Installing the MBRP system is very straightforward and can be done using common hand tools
