They directly bolt on to where the original exhaust sits and do not require any further modification. Cat back exhaust systems come with exhaust pipes, muffler and exhaust tips, so you have everything you need to replace the exhaust. The cat back is the section of the exhaust that runs from the outlet of the catalytic converter to the exhaust tips. Exhaust systems that include this often feature a large pipe running from the converter to the muffler, with mandrel-bent turns and glasspacks for reduced back pressure. Your go-to spot for information on the exhaust system, as well as mufflers, catalytic converters, pipes and sensors.

The first widespread introduction of catalytic converters was in the United States automobile market. The exhaust system is crucial to a car’s performance, especially the catalytic converter which can go bad if it’s overworked. A stock exhaust system strives to minimize the car’s materials while maximizing space. This means that the exhaust system’s performance can suffer, having to work harder with less horsepower.

Unwanted reactions result in the formation of hydrogen sulfide and ammonia, which poison catalysts. Nickel or manganese is sometimes added to the washcoat to limit hydrogen-sulfide emissions.[citation needed] Sulfur-free or low-sulfur fuels eliminate or minimize problems with hydrogen sulfide. It also boasts the ultimate in customization, including the optional 700+ horsepower Shelby GT S/C version.

This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start. Slightly lean of stoichiometric, the exhaust gases from the engine contain excess oxygen, the production of NOx by the engine increases, and the efficiency of the catalyst at reducing NOx falls off rapidly. However, the conversion of HC and CO is very efficient due to the available oxygen, oxidizing to H2O and CO2. However, the efficiency of the catalyst at reducing NOx is good, and the production of NOx by the engine decreases.

It is called a “catback” system because it starts at the catalytic converter, which is located in the middle of the exhaust system, and continues to the tailpipe. With an aftermarket performance exhaust system from CORSA, you'll be able to lose yourself in rich, deep exhaust notes you can feel in your chest with every drive. It doesn't matter if you're behind the wheel of a&nbsp
