Every vehicle comes with an exhaust system that during the short period after its first manufacturing was the newest technology on the market. Brands such as Volkswagen, Ford, Opel and others over the years have proven that they can create a vehicle that is both cost-effective and eco-friendly. However, as your car gets older (even a six-month-old vehicle is old compared to the constant advancements of technology) getting the desired performance, whether you like more power and noise or less noise and more economy, can be accomplished by installing a third-party exhaust system. One of the most talked about exhaust parts is the dump pipe exhaust.
The essential exhaust part is the connector of the headers of a manifold to the catalytic converter. Nearly all vehicles have the dump pipe exhaust part directly connected to the catalytic converter, because replacing the stock catalytic converter will neither increase the performance nor benefit the fuel efficiency. In the past, a third-party replacement with a dump pipe exhausts part was something people never considered. However, manufacturers started equipping their vehicles with a turbocharger, which creates space for an after-market down pipe that can improve the performance.
The turbocharger is a pump, and it is substantial for the pipes to have free airflow. On a lot of vehicles, both exhaust and turbo pipes have a significant number of bends. In case they are bent which is often the case with cars because of the cheap materials used to build the pipes, airflow restriction may occur.
One interesting fact is that by reducing the gas restriction, the inbuilt turbocharger may spool up faster than before, which means more power and better mileage per gallon. Because of this, reliable third-party exhaust manufacturers decided to sell massive down pipe exhausts with mandrel bends. There are numerous reasons why one should get an after-market down a pipe, but here are the most common ones.
- Driving on the road can be damaging for the exhaust pipe. Usually, the most damage the pipe endures is in the area where it goes in and out of the turbocharger. Bigger vehicles such as big trucks have enough space near the engine for installing a lot of tubes. On the other hand, smaller vehicles such as cars, do not have enough room in the engine bay, hence the need to use dump pipes.
- Whenever you decide to modify the turbo with a bigger boost pressure, you will need to get a dump pipe system. However, modern cars come equipped with a better-designed exhaust system, and in essence, they do not benefit from adding a downpipe. However, if the boost on the stock turbo increases, a need for a bigger and smoother downpipe is going to be required.
- Including dump pipe exhaust system makes for a better performance. Nearly all third-party downpipes have bigger dimensions than stock ones. Ergo, they will substantially lower the restrictions and add more horsepower.
In conclusion, for those turbo-charged vehicle owners, it is highly recommended to upgrade the exhaust with a downpipe. The only thing left to do is to find a test that proves the performance boost for your specific model before you make your purchasing decision.
