A cat back exhaust system, also known as a catback exhaust, is an aftermarket automotive exhaust system that replaces everything in the exhaust system from the catalytic converter to the tailpipe. Cat back exhausts are available in various configurations and materials, allowing drivers to choose the one that best suits their needs and preferences. An aftermarket cat back exhaust might be the perfect upgrade that can enhance your Dodge Charger’s performance and road presence. Unlike its OEM counterpart, it boasts a less-restrictive construction, so it can release more exhaust gases. A cat back exhausts is also designed to install behind a catalytic converter, so remains emission compliant. In addition, its design lets your vehicle generate a more distinct exhaust sound.

Engines fitted with regulated 3-way catalytic converters are equipped with a computerized closed-loop feedback fuel injection system using one or more oxygen sensors (also known as Lambda Sonds or sensors). Other variants combined three-way converters with carburetors equipped with feedback mixture control were used. An unregulated three-way converter features the same chemical processes but without the oxygen sensor, which meant higher NOx emissions, particularly under partial loads. These were low-cost solutions, typically used for retrofitting to older cars or for smaller, cheaper cars. Axle-back exhaust systems replace only your vehicle’s rear exhaust section, usually consisting of items behind the rear axles, like rear exhaust pipes, muffler, and exhaust tips. A
