From Overland Series to our all-new SPEQ Series, explore MagnaFlow’s latest performance exhaust systems designed for the 2024 Toyota Tacoma. Aftermarket cat-back exhaust upgrades are a relatively simple way to increase your vehicle’s power. Typically these upgrades involve installing wider piping with fewer sharp or sudden bends as a way to reduce backpressure. Backpressure is pressure opposing the desired flow of exhaust gasses. The more you are able to reduce backpressure, the more efficient the system will be, and ultimately your horsepower will increase. Cat-back exhaust refers to any part of the exhaust system that’s behind the catalytic converter.

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&nbsp
