The amount of horsepower gained from installing a cat-back exhaust system varies by vehicle and the system’s design. However, when combined with other performance enhancements, the gains can be more significant. The primary goal of a cat-back exhaust is to reduce back pressure, allowing your engine to breathe better and operate more efficiently. The factory exhausts come in mandrel bent tubes made of stainless steel or aluminized steel. Besides offering longer durability, the construction also ensures there’s free flow of gases. To improve this, you can opt to replace some parts of the exhaust system using aftermarket performance exhaust systems.

Proposition 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 900 chemicals since it was first published in 1987.

I watched a ton of videos and finally found one from Edge Autosport that went through 6 different variations of ETS setups.

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.

Another difference is with the material used in the cat-back exhaust system against that in stock exhaust systems. But the problem with a resonator is that it can cause restriction to the flow of the exhausts. In the end, this can end up lowering your vehicle’s performance. It is also more affordable and easier to install than other types of exhaust systems, including the cat-back exhaust system. Cat-back and axle-back exhaust systems are both aftermarket exhaust systems. A performance exhaust system, like the cat-back exhaust, allows for easy splitting into dual exhaust.

To maintain catalyst efficiency, the air–fuel ratio must stay close to stoichiometric and not remain rich or lean for too long. All of Milltek’s performance exhaust systems are manufactured from T304L stainless-steel
