Less restrictive catalytic converters paired with a cat-back exhaust system will offer high performance and power. Though, the level of horsepower gained is not constant across all cat-back systems. It depends on the quality and performance of the catalytic converters. Because of the better flow of exhausts resulting from the mandrel-bent tubing and the larger diameter piping, cat-back exhaust systems manage to offer better performance. IE offers catback, downpipe, and midpipes upgrades to replace individual sections of your exhaust. Installing variations of these parts allows you to dial in your exhaust volume to your preference, from sporty to aggressive.
Typically, that includes a mid-pipe, muffler, tailpipe and tips. Cat-backs generally yield increases in performance, due to the more efficient flow of exhaust through upgraded parts like larger diameter tubing and better flowing mufflers, as well as improved sound and reduced weight. For starters, the "cat" in catback exhaust system is short for "catalytic converter", a central part of your car’s emission control system, which cat back exhausts are fitted behind, hence the "back". This relatively simple mod helps to free up exhaust gas flow and improve the noise of your engine by swapping out part of your exhaust system with a specially designed
