What is downpipe?
This is the first element of the exhaust system, located right after the turbocharger in supercharged cars and behind the exhaust manifold in naturally aspirated engines (i.e. without a turbine). Most often it is made of stainless steel, and its average is larger or several times larger than the further part of the exhaust system. Often, the Downpipe also has a vibration damper (i.e. a flexible connector) and welded threads for screwing in the lambda probe. The downpipe can also be purchased with a catalytic converter with an increased throughput of exhaust gas standards of 100 or 200 cpsi and compliant with Euro 2 to Euro 6 standards.
What does downpipe give you?
The increased diameter downpipe without or with a sports catalytic converter significantly increases exhaust gas flow, which translates into more efficient turbine operation. The downpipe together with the intake system is often the first mechanical intervention to generate more power from the engine.
How does downpipe work?
Downpipe's task is to transport the exhaust gases falling out of the turbocharger to the further part of the exhaust as quickly as possible. It is worth mentioning that the exhaust gas reaches a speed of 300 m/s, so the downpipe is designed in such a way that the bends are as small as possible and the exhaust gas flow is as free as possible.
Is it worth installing Downpipe?
To sum up - the sports Downpipe is a good investment for people who want to easily increase the performance of their car or the stock Downpipe is not enough to achieve the desired power. Attention should be paid to the exhaust system, which is located behind the above-mentioned element. For example, the use of a downpipe without a catalytic converter with an increased diameter will not do much if the system includes a serial chamber silencer. In addition, the exhaust diameter will be, for example, 50mm. In addition, in the serial exhaust system, we can find, for example, exhaust narrowings near the rear beam, which significantly affects the free flow of exhaust gases.
