BMW M4 Remus Exhaust Tuning Revozport Carbon 21

Sports mufflers are part of sports exhaust systems. They can increase performance, especially in combination with a complete sports exhaust system, and typically bring a really good engine sound with them, which makes them very popular in the tuning scene! However, before installing a sports rear muffler, it does not hurt to be well informed about its structure and operation.

Construction of a sport muffler

Of course, the exact structure of a sport muffler varies depending on the manufacturer, material and product, but they all roughly correspond to the same principle. Instead of the chambers installed in conventional dampers, pipes are installed in sports rear silencers through which the exhaust gases are directed. The pipes are provided with holes. The number and size of the holes varies from damper to damper. They ensure that the sound can escape from the pipes. Between the outer shell of the damper and the pipes may be incorporated among other things metal wool as a filling.

Function of a sports rear silencer

Conventional mufflers mainly aim to dampen the sound, as can be easily inferred from the term. The chambers ensure that the waves are shortened until they interfere. In this way, the sound waves virtually neutralize each other and the combustion noises are barely audible. However, the functionality of normal silencers is a thorn in the side of many motorsport enthusiasts. The routing into the chambers of the rear silencer creates an exhaust back pressure, since at full load more exhaust gas flows out of the combustion chamber than can be routed through the chambers of the silencer.

The resulting excess exhaust gas pressure no longer allows the exhaust gases to escape efficiently from the combustion chamber. This results in a performance restriction of the engine, since the remaining exhaust gases mean that less oxygen can flow into the combustion chamber. The pipes installed in the sports rear silencers ensure that the exhaust gases flow through more quickly. This reduces the exhaust back pressure and increases performance. The problem, however, is that the middle silencer and the catalytic converter often ensure that the exhaust gases continue to back up. For an increase in performance, you should therefore consider converting the entire exhaust system.

The sound!

By guiding the exhaust gases into the pipes installed in the sport rear silencer, the engine sound changes drastically, which makes it interesting even without the installation of a uniform sports exhaust system. The pipes do not allow the sound waves to interfere so well. A sports rear muffler can make your vehicle sound much sportier! There is a wide selection of sport mufflers on the market for many vehicle models. So one can its sports rear silencer after the desired criteria such as manufacturer, price or ABE certificate choose. If that's not enough, you should CutOut system obstruct. However, legal use in road traffic is usually history!
