We all want bang for our buck, pounds for our pennies and miles from our cars.
Many of us are also after more umph and roar from our exhaust.
So what’s the perfect part for both?
A downpipe is a good place to start, more sound, more roar and more power, means it definitely sounds like a good way to go.
The question is, how?
In this blog we will look at what a downpipe is, how it works and common assumptions made about downpipes.
What is a downpipe?
A downpipe for your car is a part that connects to the turbine housing and the catalytic converter; unless it has a decat.
In which case it will connect to the decat pipe, and has a primary job of directing gasses from the vehicles turbine housing into the exhaust system.
This is by minimising obstructions and collisions.
They can also increase the sound of your car and the pitch due to more effective gas flow.
What does a downpipe do?
Its job is to move the gasses through to the exhaust system as efficiently as possible to improve the performance of the vehicle.
The more gas that leaves the turbine housing, the more air the engine can breathe in.
This equates to more power.
A turbo charged car typically will benefit from an aftermarket downpipe due to the improvement of the flow of gasses into the exhaust system and consequently gaining a potential 10-20bhp.
So, how does an aftermarket downpipe work?
If the exhaust downpipe isn’t smooth inside and a consistent diameter then this can obstruct the flow of gasses and reduces the effectiveness of the downpipe.
Do downpipes make a car louder?
This is when you can hear that roar and feel that rumble coming from your exhaust.
Will an after market downpipe fail an MOT?
If more power is what you are after and a downpipe doesn’t feel like it will give you enough growl and enough power, then you may be looking at a full exhaust system.
There are a few to choose from such as catback exhausts that connect to the catalytic converter or turboback that connects to the turbo.
