Conclusion. Upgraded downpipes provide great increases in horsepower and torque on turbocharged vehicles by allowing exhaust gasses to flow easier as they leave the turbo. Paired with the appropriate software, a downpipe can provide significant gains and make a vehicle more fun and engaging to drive.
Does downpipe affect the engine?
A downpipe is put in place because it allows the turbo aspect of the engine to be more effective. The downpipe steers gases away from the turbine, creating more uninterrupted power.
Does a downpipe increase boost?
From what I've gather by reading between the lines of everyone's feedback is that with a downpipe, sports or decatted, it's not about the overall numbers but the fact it allows a freer flowing exhaust, hence less strain on the turbo's load, with or without added boost..
Does Catless downpipe increase horsepower?
Catless downpipe provides even more horsepower gain than catted downpipe. You can expect catless downpipe to provide 50 horsepower with tuning (25 hp without). Performance is the biggest advantage for going catless.
Do downpipes add sound?
Aftermarket downpipe definitely makes a car louder and sound more aggressive. This is because aftermarket downpipes are louder than stock and they reduce the backpressure in exhaust. Allowing sound waves to travel smoothly without collision.

Aftermarket Downpipe makes turbo louder louder because it's wider – allowing sound waves to travel easier without collisions. Downpipe comes in two types: catted downpipe or catless.
Does a downpipe increase fuel consumption?
Registered. it all depends on how you drive, the potential for slightly better mpg when cruising should be there after a downpipe and software, however if you are driving hard expect worse mpg.
How much HP gain from downpipe?
Downpipe For Horsepower: Worth It? If you are installing a downpipe for the horsepower gain, then it's definitely worth it. Combined with a tune, you could see a major boost in horsepower – about 40 to 50 horsepower gains. After installing a downpipe, the exhaust flow in your car will be improved considerably.
How much horsepower do lower downpipes add?
It's generally accepted that installing a downpipe will add just 10 to 20 horsepower, but that gain is noticeable when the engine is revved up.
What is a high flow downpipe?
Similar to cattless downpipes, high-flow catted downpipes will allow your turbos to spool faster and deliver more power. However, as you likely assumed, these downpipes have catalytic converters and are more restrictive than catless downpipes. They still provide relatively solid gains for turbo spool, power, and sound.
Do I need tune after downpipe?
Does Downpipe Require Tuning? Downpipe does not require tuning to work. If you really don't want a tune or you can't afford it – you can install downpipe without a tune. The main reasons why I recommend you tune after installing a downpipe are horsepower and check engine light.
Why does a downpipe need a tune?
Registered. Less backpressure from a less restrictive downpipe = turbo builds boost faster = more air into the engine from the turbo = you absolutely need a new tune to compensate for that.
Is downpipe same as headers?
The downpipes have the catalytic converters. The downpipes connect to the exhaust manifolds(headers)and run to the cat-back, or, the section of pipe which has the resonators and mufflers and tips.
Do downpipes cause check engine light?
Will Downpipe Install Cause Check Engine Light (CEL)? You are definitely going to cause a Check Engine Light (CEL) when installing catless downpipe.

Catless downpipe is not legal in every state of the US (almost in the majority of countries, I would say). Catless downpipe is illegal to drive on the street because of high emission concerns. If you are planning to install a downpipe for your daily driver, then you should look for a catted downpipe instead.
Do you need a turbo for a downpipe?
If your vehicle is equipped with a turbocharger, a downpipe may be part of your solution. The downpipe bolts directly to the turbine housing and helps direct exhaust gases through the rest of the exhaust system. Most factory downpipes will have at least one very restrictive catalytic converter.
How much HP does a straight pipe add?

MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).
Do downpipes add HP?
An aftermarket downpipe (MATOLA Performance Downpipe) usually larger in diameter and it either use a catted or catless configurations. Which able to create more power to your vehicle because it with high flow unit which allowed the turbo move gases away from the turbine more efficiently.
Does downpipe decrease mpg?
Not sure how many miles you have on your car, but it can make a difference. catless downpipes would either help, or not change mpg's at all (probably help) given identical conditions/acceleration. if you have a tune, you dash mpg's may not be accurate as sometimes the actual usage varies from what the car thinks.
Does cold air intake make turbo louder?
Quick answer – Yes. The sound of your car will be louder and more aggressive with a cold air intake. Instead of loudness though, a cold air intake changes the sound of your car engine. You will clearly hear the sound of air flowing into the intake – especially when you rev up the car and then release the throttle.
Does a Catback exhaust come with a downpipe?
