What is a Downpipe?
What is a Downpipe?
The downpipe, which is the pipe that goes down, is part of the exhaust. This pipe goes down the outlet of the turbo or the exhaust manifold. In this way, the exhaust gases are transported to the downstream side and sent to the rear of the vehicle by combining with other parts of the exhaust system under the vehicle.
Does the downpipe increase power?
Above the downpipe are catalytic converters. These allow it to find substances in the exhaust that are harmful to the environment and make them less harmful.
There is more than one catalytic converter in vehicles. Apart from the catalytic converters on the downpipe, towards the rear or middle part of the vehicle, there are also second or third converters. The reason they are above the downpipe is that they can heat up faster than they are closer to the exhaust gas outlet and the engine. In order for this function to be fully formed, the temperature must be quite high. There is a catalytic converter on the downpipe to reduce emissions when the engine temperature is low. Since this heats up faster compared to other converters, it reduces emissions when the engine is cold. But after the engine temperature rises, there are even larger catalytic converters on the exhaust system, which is its main function.
They have a closed and multi-honeycomb internal structure and cause the exhaust gases to create pressure by compressing and not being able to go further back.
Drivers who want it to be more efficient cancel the catalysts and turn the downpipe into a straight pipe. Another reason they do this is to have a more beautiful exhaust sound. Since the exhaust gases are trapped and pass through, it distorts the sound waves acoustically and makes them quieter. When we look at it, catalytic converters also take on the role of silencers. The downpipe creates a fuller sound when the catalytic converter is removed and turned into a straight tube shape. This process is a process that drivers who like modified will like.
