Yamaha Rhino 660 - Exhaust System | Pro-Tec
Dyno developed and tested, Pro-Tec's 2 into 1 into 2 balanced flow design will provide a 23% gain in horsepower and a significant increase in low RPM torque.
Rubber mounted for reliability and ceramic thermal coated for durability the Pro-Tec Mach-1 exhaust system includes a removable U.S. Forestry approved spark arrestor and an optional adjustable sound suppression system that allows you to adjust the sound output of the exhaust system.
The Pro-Tec adjustable sound suppression system is exclusive to the Pro-Tec Mach-1 exhaust system and will not be found on any other aftermarket exhaust systems.
When used in conjunction with an aftermarket CDI you will see a speed increase of up to 31% on a Rhino with a stock engine!
*An even quieter sound suppression insert is also available separately to reduce the sound output even further!
