It is important to note, however, that going too large may cause a dip in performance when gases pile up and exit the system slower resulting in torque, rpm, and horsepower loss. After the emissions are channeled out from the cylinders by the exhaust manifold, they are deposited into different catalytic converters.

A catback exhaust system is a type of aftermarket exhaust system that replaces the muffler and tailpipe of a vehicle. It is called a "catback" system because it starts at the catalytic converter, which is located in the middle of the...

Cat-back exhaust systems replace all the components after the catalytic converter, sometimes referred to as the cat. Now you can upgrade your downpipe or mid-pipe depending on your applications. Some cat-back systems will include a mid-pipe depending on your cat layout. And when you want to make more power and take your vehicle to the next level, then you will be ready for an exhaust manifold. Available only from Mallett Performance Cars, this exhaust system is made from 304 stainless steel and features the highest quality mufflers and resonators.

A cat back exhaust system, also known as a catback exhaust, is an aftermarket automotive exhaust system that replaces everything in the exhaust system from the catalytic converter to the tailpipe. Cat back exhausts are available in various configurations and materials, allowing drivers to choose the one that best suits their needs and preferences. An aftermarket cat back exhaust might be the perfect upgrade that can enhance your Dodge Charger’s performance and road presence. Unlike its OEM counterpart, it boasts a less-restrictive construction, so it can release more exhaust gases. A cat back exhausts is also designed to install behind a catalytic converter, so remains emission compliant. In addition, its design lets your vehicle generate a more distinct exhaust sound.

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.

The difference is that the dual exhaust system has two exhaust systems on one vehicle. Meaning, when modifying your exhaust, never start from the front of your turbocharged vehicle with a downpipe or with headers on your naturally-aspirated platform, you will create a bottleneck in the flow. By starting with a cat-back first, your exhaust gases will flow more freely if the rest of your system is stock.

The difference in fuel economy is, however, more obvious while driving on a freeway. They also do not offer the best performance due to many reasons. If you're looking for an off-road exhaust with&nbsp
