Car Downpipe

What Is a Downpipe and Why Do You Need One?

When thinking about how to improve your vehicle, many view aftermarket exhaust systems upgrades as a necessity. Candidly, most vehicle owners get overwhelmed when considering all of the custom exhaust system options. So, the Performance Muffler team wants you to be as educated as possible when it comes to your vehicle. That’s why we’ve explained several automotive upgrades in our blog, and in this article, we’ll break down why you might want a downpipe.

So, What’s a Downpipe?  

A downpipe is a section of tubing to direct exhaust gasses. It connects where exhaust steam escapes to the exhaust system’s start. Specifically, this is bolted to the turbine housing. A downpipe better allows spent gasses to exit the engine. Plus, they contain catalytic converters that reduce harmful gas emissions.

Understanding the Downpipe that Comes with Your Vehicle

Some high-end, supercharged vehicles come with a downpipe system. The problem is that most vehicles that roll off the lot from their manufacturer aren’t ready to be tested to the limits. Gearheads might want to install an aftermarket exhaust system alteration.

Specifically, you can remove the original downpipe and replace it with an aftermarket version. This typically includes a downpipe with a larger diameter or high flow catalytic converter. With the right mechanic, however, you can do more with your downpipe and entire exhaust system.

Why Have a Downpipe?

A downpipe helps the engine’s turbo operate more effectively. Steering gasses away from the turbine, a downpipe helps create better power. You’ll be able to notice this shift in power on higher-end vehicles.

Furthermore, aftermarket downpipes help your vehicle even more. They’re less restrictive, increasing power and fuel economy. Plus, you can notice a better engine lifespan since it’ll reduce the engine temperature. You’ll likely even enjoy your ride more with a non-factory-issued downpipe. The open road is yours!

Downpipe: Cat vs. Catless

Another important note for drivers looking to upgrade their downpipe 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.

Benefits of a Downpipe

We want to explicitly list the benefits of a downpipe, in case you aren’t sold yet. 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.

Other Exhaust System Improvements

If a downpipe doesn’t sound appealing to you, fear not. There are several other aftermarket exhaust system improvements you can make. If you want to change the sound, maybe you can do a muffler delete or add exhaust tips. If you want to improve performance, consider a cat-back exhaust system or different exhaust pipes.
