Description
A cat-back exhaust system replaces all components from the catalytic converter to the tailpipe, typically including the mid-pipe, resonator, and muffler. This system is designed to improve airflow after the catalytic converter, reducing back pressure and enhancing exhaust flow for better performance. Cat-back systems often provide a noticeable increase in horsepower and torque, a deeper exhaust note, and improved fuel efficiency—all while maintaining emissions compliance.
It’s a popular choice for enthusiasts looking to boost performance without modifying the catalytic converter.
