What Does a Mustang EcoBoost Catback Exhaust Do?
A Mustang EcoBoost catback exhaust replaces the factory exhaust system from the catalytic converter to the tailpipes, allowing exhaust gases to flow more freely. By reducing backpressure, it helps the turbocharged 2.3L EcoBoost engine breathe better, resulting in improved horsepower, torque, and throttle response. In addition to performance gains, a catback exhaust transforms your Mustang’s sound profile, delivering a deeper, more aggressive exhaust note that enhances the driving experience.
