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.

Finally, the catalytic converter can become fouled over time, resulting in a loss of power. This can be remedied by having the converter cleaned or replaced as needed. When it comes to choosing the right cat back for your car, there are a few things you need to keep in mind. First, you need to make sure that the cat back you choose is compatible with your car's make and model. Are you an aggressive driver who likes to take corners at high speeds?

Our straight-through brushed-finished mufflers are configurable to your desire, smoothing the exhaust note to a deep growl, without adding restrictions, rasp or drone. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3" to dual 2.5" rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. In addition to high-quality materials and components, the design of each high-performance exhaust system allows for easy, bolt-on installation right out of the box. CORSA exhausts require no welding and can mount directly to your factory connections.

Considering cat-back exhausts replace more restrictions, they typically offer increased performance and noise compared to axle-back systems
