2004-2009 Yamaha YFZ450 - Performance Full Exhaust System.
Designed and developed for the all out racer as well as the power hungry recreational enthusiast.
Pro-Tec Mach 1 exhaust systems and Mach 1 spark arresters will provide maximum usable power. (removable spark arrestor is included) Dyno developed to confirm power output and track tested for proven reliability.
All Pro-Tec ATV exhaust systems and spark arresters are thermal ceramic coated for temperature control and a polished finish.
Note: The stock exhaust system weighs 11 pounds. Our mach 1 exhaust system weighs only 6.4 pounds making a difference of 4.6 pounds less than the stock pipe. More power, less weight, better value!
Mach 1 exhaust systems by Pro-Tec are also available with the optional A.N.S. The Pro-Tec Adjustable Noise Suppressor is quickly adjusted to reduce decibels in environmentally sensitive areas. No caps to remove. No parts to add. Adjustments are simply made by spinning the inner plate to the desired position and resetting the lock bolts.
