The anti-reversion muffler is designed to catch the reversion pulse from the cam with a large overlap. These mufflers build torque off idle to wide open throttle. Increases as much as 60 ft lbs of torque from 2,000 to 5,000 RPM have been seen. This product enhances restate capabilities & bottom end torque in crate and open engines. For 3-1/2" collector
