About Cat-Back Systems

Cat-Back refers to the portion of the Exhaust System from the outlet of the Catalytic Converter to the final vent to open air.

This generally includes the pipe from the Catalytic Converter to the Muffler, the muffler, and the final pipe tip to open air.

Performance Cat-back exhaust systems are a very popular aftermarket performance enhancement. Using larger diameter pipe than the stock system and mandrel-bent turns that allow the exhaust gas to exit with as little back pressure as possible.

Some Cat-Back systems are engineered more for show than functionality, being tuned to enhance the engine sound at lower rpm.
