In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.
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.
We match the exit size to the size exhaust you ordered, so if you are ordering this after the fact, please include the exhaust size you have in your order. Replaces the OEM catalytic converter with a free flowing pipe. Completely straight through (no bottleneck), free flowing mini-muffler and pipe. Replaces the OEM catalytic converter with a 3" metal substrate core high-flow performance cat and our mini muffler. The metal core is our highest flowing cat available and it will
