The system’s Scavenger Series X-pipe crossover is engineered to improve exhaust scavenging, which helps increase horsepower and torque by efficiently evacuating exhaust gases.

Tailpipes are designed to fit precisely using factory hanger locations, ensuring a secure fit and a clean, stealthy look that integrates seamlessly with the vehicle’s original styling. The use of factory exhaust bezels for tailpipe exits preserves the Challenger’s aggressive yet refined aesthetic.
