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.
It typically includes a rear pipe, resonator, and muffler that all attach after the last catalytic converter. The turbo-back system is the most complete system you can buy. It replaces all of the components that the previous two systems that we’ve talked about and also upgrades the downpipe. The downpipe is the first piece of exhaust piping that comes after the turbocharger and it also houses the catalytic converters on all L15 powered 1.5T Civics and Integras. From a sound and performance perspective, you’re going to get the most of both compared to the other two versions mentioned before.
When the exhaust mode is placed in "Sport" mode the exhaust system broadcasts an "Xtreme" level sound 6 decibels louder than the stock exhaust system. As the driver adjusts the exhaust mode to the "Normal" level, the exhaust produces an exhaust note more closely resembling a CORSA "Sport" level exhaust note.
