As Used, Tried and Tested on our OWN Leon 5F Development car. Fitment is excellent, high quality, UK Manufactured product, With options to suit everyone!

This 4" De-cat downpipe was designed to be the first and last downpipe you'll need to buy for your car, regardless of the size of the hybrid that you attach it to!

When you start pushing the OEM turbo, exhaust gas temperatures start to rise (this is the same for the hybrids). This downpipe is about as close to having a bonnet exit exhaust as you can get, without the associated hassle of a section 59!

Key points to bear in mind :

• This downpipe is only available with a quality OEM style soft flex. The same style as the one it rolled out of the factory with. Using any other style of flex will simply turn you turbo and downpipe into another engine mount.

• The factory downpipe support bracket on the back of the engine block has been utilised, helping to reduce stresses being transmitted to the turbo and V band connection. 

• Designed and manufactured in England using European sourced 304 stainless steel. 

• Mandrel bent in house using computer controlled machinery.

• All Tig welds back purged.

The results speak for themselves :

• Lower exhaust gas temperatures

• Earlier turbo spool, giving power earlier and holding that advantage across the rev range

• Reduced under bonnet temperatures

• Reduced drone

Its design allows fitment to cars with completely standard exhausts (with the use of the adapter available separately) and cars with most 3" aftermarket exhausts (adapter also available separately) We've highlighted the 3" adapter option, because whilst we would like to be able to send one adapter to fit all 3" exhausts, it's not that simple. The 3" adapter that we offer works with most of the big brands.   

 The Catalyst version of this downpipe will need stage 2 software due to it's positioning. 

**GPF explanation- EURO spec cars 2019MY onward have GPF filters. The rest of the world does not. By selecting the GPF bracket option, you will receive a bracket which will aid fitment. The downpipe will not have GPF temperature sensor bosses. They will need to be mapped out completely**

FAQ's

Q. Will this work with the standard factory turbo?

A. Yes it will. This downpipe will allow the turbo to spool earlier than most standard "Flash" files will be able to cope with. This proves that the downpipe is doing what it was made to do. 

Q. Will the catalyst version pass an inspection?

A. It will pass the UK MOT machine sniffer test but it will still need stage 2 software due to it's positioning. The only truly road legal downpipe for you car is the one which it left the factory with. 

Q. Can I fit the de-cat version to a car that hasn't been mapped? 

A. We always recommend that people get their car tuned to match the hardware on the car. Proper tuning will get the best from this downpipe and the other supporting modifications you have on your car. If you drive the car without getting it tuned, the ECU will see an over-fuel condition and the ECU will reduce fueling to compensate, thus causing a lean condition. 

Q. Do I need to heat wrap or ceramic coat this downpipe?

A. That's entirely up to you. Due to it's size, it runs much cooler than any other downpipe. We do however recommend heat shields where appropriate. Ultimately, we recommend a common sense approach to heat management. 

Q. How much louder than the stock downpipe is it?

A. Whilst this downpipe is so much bigger than standard, it's not so much noisier. In fact, one of the most common pieces of feedback received is how it's quieter than a 3" aftermarket downpipe that it is replacing. Many people are also saying that it's curing drone which was previously present!

Q.Does it fit the standard factory turbo?

A. Yes.

Q. Will it make the standard turbo spool faster?

A. The downpipe will make all turbos spool quicker but this will be most noticeable on larger hybrids. The car must be tuned to accept this earlier onset of boost.

Q. Will it fit with the aftermarket exhaust that I'm buying?

A. If that Catback exhaust was designed to work with the OEM downpipe, it will work with our downpipe if you choose the appropriate adaptor from the options.
