What the Exhaust downpipe Is?

If you want to increase the power of your vehicle, the exhaust downpipe is a great option. If the vehicle is already equipped with a turbocharger, you can also choose the exhaust downpipe to increase the vehicle’s power. The exhaust downpipe is the components which is bolted directly to the turbine housing and helps direct exhaust gas through the exhaust system. Most exhaust downpipe manufacturers have at least one catalytic converter in the exhaust downpipe. They do a good job of cleaning the exhaust gas, but the restrictions are strict, otherwise it will lead to potential power loss.

The Function of the Exhaust downpipe

The exhaust downpipe of a turbocharged vehicle directs exhaust gas from the turbine casing to the exhaust system. The diameter of the exhaust downpipe on the market is usually larger, either using a high-flow catalytic converter, or removing the catalytic converter completely. By removing the factory’s exhaust downpipe and replacing it with a high-flow device, you can make the turbine discharge gas from the turbine more efficiently, thereby generating more power. The factory’s exhaust downpipe is a bottleneck in performance. Now that the factory restrictions have disappeared, you can increase the power of the vehicle by changing the exhaust downpipe. If you want to get the most power without changing your turbocharger, the exhaust downpipe is the key.

Classification of Exhaust downpipe

There are usually two configurations of exhaust downpipes on the market, one is a catted exhaust downpipe, and the other is a catless exhaust downpipe. The catted exhaust downpipe uses a high-flow catalytic converter, while the catless exhaust downpipe removes all catalytic converters. For a catted exhaust downpipe, the catalytic converter purifies the exhaust gas as it passes through the catalyst, which means that the odor of the original exhaust gas is reduced. If you choose a catless exhaust downpipe, please note that the vehicle will be smelly, as this exhaust is not purified before leaving the vehicle.
