Up Pipe Vs DownPipe – What Are The Major Differences?

The up-pipe connects the exhaust manifold with a turbo, which it accepts gasses from various parts of your engine. The downpipe takes those same streams and leaves them at their destination: without this connection, there would be no way for any energy generated by burning gasoline.

A turbo is an important part that can boost your horsepower. There are two types, up-pipes and downpipes; they’re required for installing a Turbo which increases the power generated by combustion in cars’ engines by 100%. Up-pipes and downpipes are both essential for any efficient engine. The difference between them lies in the way they work, so let’s find out more about each one of them.

What Is a Turbocharger?

Up-pipes and downpipes are the required parts to install a turbo. So before we can talk about them, it is important that you understand what “turbo” means as well as how this car part increases horsepower – an additional 100 HP (a lot) may be achievable with one installed. You see Cars generate power by creating combustion in their own chamber; however, there’s always more room for improvement when temperatures start getting low or inefficient because of gas limitations.

The turbo takes in the surrounding air and compresses it before feeding that fresh, clean supply into your car’s engine. This process is powered by the turbine from within a combustion chamber where toxic exhaust gasses are produced as byproducts of energy production – but don’t worry. These same forces will push outwards against these harmful particles so they stay mixed with intercooler fluids instead of flowing outside towards us humans waiting to breathe them down our necks.

What Is Up Pipe?


The up-pipe is the last piece of tube that consolidates all four manifold tubes and carries their exhaust gas into a turbine housing. The Prosport header pictured above combines both headers in one package, sold together as opposed to separate units for easier installation. Up-pipes are an excellent way to improve your engine’s performance. They allow the airflow through it more easily, dropping exhaust gas temperature and boosting horsepower or torque in return.

What Is DownPipe?

Up Pipe Vs DownPipe

If you have a turbocharged vehicle, it’s important to consider installing an exhaust system. The downpipe connects the turbine housing and helps direct hot gas through other parts of your car or truck engine bay for better performance by reducing back pressure caused by restrictive catalytic converters. The factory downpipe is a chokepoint for performance. By removing it and replacing it with an aftermarket high-flowing unit, you are allowing the turbo to move gases away from its turbine more efficiently which creates even greater power output.

Up Pipe vs. DownPipe

Gases flow

Uppipes allow the flow of gases from your engine’s exhaust manifold into a turbo. And then downpipes take those same heated particles out, away from any sensitive parts inside or outside on a vehicle that could be damaged by them.

Catalytic converter

The catalytic converter is a key part of your car’s emissions system and it converts toxic exhaust gases into non-toxic ones. Up-pipes and downpipes are equipped with catalytic converters that help turn toxic exhaust gases into non-toxic ones.


A tune can make your car more powerful.  A tune can significantly increase HP. With a tuning session, I expect an up pipe or downpipe for example will provide 30hp and 50 respectively in addition to all other modifications that have been made like exhausts etcetera.


In my opinion, if you want to increase your car’s horsepower by a good amount then yes. Just make sure that it has been catted and brought in for tuning after the installation of an intake or exhaust system is complete so as not to affect any other aspects such as performance exteriorly with modifications installed on them already.


The aftermarket up-pipes and downpipes are not legal in most states. They’re designed for use on race tracks or off-road, which means they may be against the law where you live depending on your state’s laws about modifications to vehicles that can cause them trouble when driving legally within those boundaries but this doesn’t mean it won’t work.

Pros and Cons of Up-Pipe


  • Enhancement your horsepower
  • Authentic sound of your vehicle engine
  • Reduce the weight profile of your vehicle
  • Universal kits are available to help you fit


  • Lack of flexibility with these design
  • Produce a ton of emission

Pros and Cons of DownPipe


  • Increase horsepower
  • Louder exhaust sound
  • Works well with other mods
  • Relatively cheap mode
  • No check engine light if tuned


  • It has a slightly unpleasant exhaust smell
  • Void warranty on related parts
  • Not street legal


Is the Front pipe the same as the downpipe?

The cat converter is what you need if your vehicle has a downpipe. It’s attached to the front pipe, which connects it with everything else under the hood- including gas cylinders and engine valves.

Do downpipes increase horsepower?

upgraded downpipes are a great way to increase horsepower and torque on turbocharged vehicles by allowing exhaust gasses to flow more easily as they leave the turbos.

Does a downpipe increase fuel consumption?

The downpipe is a section of the exhaust that goes from your car’s engine and diverts some of its waste products into less harmful substances. For most vehicles, this passage will be incorporated with their catalytic converter so you can’t really change it without also replacing both pieces together as well.

Final Words

The up-pipe and downpipe are both essential for optimizing your boost. The first thing they do is allow exhaust gases to flow from the engine’s manifold into a turbo, which then sends them on their way out through an attached muffler or resonator pan as needed depending upon where you live in relation to other cars that may be chasing evaporation points too closely

So, which is the best for your car? Well, that depends on a variety of factors. If you have a turbocharged engine, then you’ll need to use a downpipe. If you want improved performance and sound from your exhaust system, then an up-pipe may be the best option for you. We hope this article has helped clear up some of the confusion about these two types of pipes and given you the information you need to make an informed decision about which one is right for your vehicle.
