FEATURES
The Traxxas Resonator aluminum tuned pipe for Revo is specifically engineered to fit right in the chassis and complement Revo's racing engine.  The single-chamber design dramatically increases bottom-end punch by nearly 20% between 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.
