Cat-Back Exhaust Systems & Mufflers

A cat-back exhaust system refers to an exhaust kit that connects to the back of the catalytic converter. This includes the inlet, pipes, muffler (s), as well as the exhaust tailpipe exit and tips. Performance cat back systems can upgrade the exhaust from a single to dual exhaust configuration. Included in most catback systems are hangers, clamps, gaskets, and any other necessary hardware to complete installation.

High performance cat back exhaust systems typically add anywhere from 10 to 35 horsepower to the rear wheels. The amount of power improvement realized is dependent on how much reduction in exhaust flow restriction is achieved by adding the catback exhaust kit.

Car and gas / diesel truck exhaust systems can range anywhere from under $200 to as high as $4000 or more depending on how complicated the design is as well as the type of material the system is made from (for example stainless steel or aluminized steel).

The best cat back exhaust system depends on a number of factors. These factors include the year, make, model, and engine of the vehicle, the type of material the system is made from, the price, as well as how the cat back exhaust sounds to the driver, as the tone and sound of the exhaust is a personal preference. All cat-back exhaust systems available from JEGS are made from high quality components and assembly.

Most car, SUV, and truck exhaust systems are installed similarly. The first step is to remove the old exhaust from the back of the catalytic converter to the exhaust tips. The connection to the converter can either be unbolted or unclamped. However, for some applications, it will need to be cut off with a hacksaw or other tool. The rest of the exhaust is suspended from under the vehicle by hangers, so disconnecting them will be required. Once everything is removed from the vehicle, the installation can begin. Starting from the converter back, put all of the exhaust pieces into place and loosely tighten any connections. Do not tighten anything beyond the point of parts being able to twist or rotate as "tweaking" of the exhaust will be required to get everything lined up and correctly in place. Once the exhaust is positioned, all of the connections can then be tightened down and work double-checked. Finally, start the vehicle and listen for any exhaust leaks or unusual sounds. If none are heard, a test drive can be made to confirm the exhaust is installed correctly.
