These 3/4 Systems are manufactured from polished 304 stainless steel and feature a deep draw polished stainless steel end cap. The muffler itself is quite innovative. It features a multi-staged construction that starts with a straight baffle that initially flows into a large volume perforated baffle chamber. From there, gases flow into a floating baffle that is integrated into the end cap. Inside the floating baffle is a USFS-approved spark arrestor. Low 96db sound levels keep the RS-8 friendly on the trails or the track. The overall design produces big increases in power and torque.
