How Does An Exhaust Down Pipe Work?

The Exhaust system is responsible for converting your engine`s harmful emissions into less harmful substances. It is also in charge of transporting your vehicle`s emissions through the exhaust system and out the Tail Pipe. An exhaust down pipe is the piece of pipe that connects the exhaust manifold, which collects and funnels all of the engine`s gases into the rest of the exhaust system, and the Catalytic Converter, which converts the engine`s harmful gases into less harmful substances. Down pipes are specifically designed with a large diameter so the engine`s gases can travel quickly through the exhaust system without any restrictions.

Benefits of a Downpipe.

A downpipe helps the engine`s turbo operate more effectively. Steering gasses away from the turbine, a downpipe helps create better power.

Apart from better performance, a downpipe can alter the vehicle`s sound. A less restrictive downpipe with larger diameter piping enhances sound, making a more enjoyable and memorable ride. Some car models will see an improved engine bay appearance. With less wear and excessive heat under the hood, your engine can function better and therefore look better.

Downpipe: Cat VS Catless

Another important note is the distinction between a cat or catless downpipe. This difference is pretty simple: cat downpipes have catalytic converters, whereas catless downpipes don`t. Catalytic converters alter the gasses within the exhaust system so they`re safer when released into the environment. So, a catless downpipe will have a noticeable odor, because the exhaust emissions aren`t significantly converted. In other words, they`re not being cleaned. For that reason and since it helps the environment, most people choose the catted version of a downpipe.
