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.

Made from traditional steel that’s been coated on all sides with aluminum-silicon alloy, these systems are very strong thanks to the metallurgical bond which still provides a level of corrosion resistance. While the aluminum coating reflects heat well, the steel can corrode if the aluminum layer is chipped or scraped off. Most cat-back systems will come in either an aluminized or stainless steel version.
