The single-chamber Resonator aluminum tuned pipe is precision-engineered on the dyno to increase bottom-end punch by nearly 20% between 10,000 and 15,000rpm, and continues to pull strong with a 10% increase from 15,000 to 30,000rpm. It’s perfect to provide that extra snap of acceleration off the line. All Resonator pipes are fully polished to a beautiful mirror-chrome finish with a laser etched logo. Includes mounting hardware.
