The term reverses cat exhaust can be defined as the part of the exhaust system that follows the last catalytic converter in the system. It usually consists of a rear pipe, resonator and damper, but depending on the make and model it can also contain a centre pipe, X pipe, H pipe or Y pipe.
Adding a replacement cat can offer several benefits, the first being better performance. The secondary purchased exhaust system is designed to flow more freely than your standard exhaust. They usually include larger diameter tubes and high-quality mandrel bent tubes for more laminar flow. You can also visit xforce.eu/ to get cat-back exhaust system.
This change can result in a decrease in backpressure in the engine manifold, meaning the engine can breathe a little easier and release more horsepower and torque. How much horsepower it gets depends largely on the design of your factory exhaust system and the quality of the catalytic converter in front of it.
If the series catalytic converter is sufficiently limiting, less power can be obtained from the exhaust system of the catalytic converter. If a standard catalytic converter can emit large amounts of exhaust gases and create too many restrictions, then the exhaust system of the catalytic converter should provide a good performance boost.
Increased fuel consumption is often seen after installation. This is because the engine doesn't have to work so hard that it pushes the exhaust gases through the pipes. This reduces the overall load on the engine, resulting in higher efficiency and MPG. This increase in fuel consumption usually occurs when driving on the highway, but is sometimes seen when driving in the city.
