Milltek Downpipe & De-cat for Volkswagen Up! 1.0TSI 90PS (3 & 5 Door) (2016 onwards) – Maximum Flow, Motorsport Use
This is Milltek's large-bore downpipe and de-cat for the Volkswagen Up! 1.0TSI 90PS (3 & 5 Door). It replaces the factory downpipe with a larger-bore pipe and removes the catalytic converter entirely, clearing the single most restrictive point in the exhaust for the biggest flow gain available at this position in the system. It's usually fitted alongside a Stage 2 remap, since the ECU needs to be told to expect the different readings the lambda sensors give once the cat's gone. It's offered in versions to suit the factory or a Milltek system, so you can pick the setup that suits how the car's used.
It's built for owners already committed to a serious power upgrade rather than a casual bolt-on, so pair it with the matching Milltek cat-back system for the full effect.
Because it removes the cat, it's intended for off-road and competition use. A de-catted car will fail an MOT emissions test and isn't legal to use on UK roads.

Installation

Will it fit the Volkswagen Up! GTI 1.0TSI 115PS (3 & 5 Door)?
Yes. Milltek lists this part for the Volkswagen Up! GTI 1.0TSI 115PS (3 & 5 Door) as well as the other models in the fitment list above.
Is it road legal?
No. Removing the catalyst means the car will fail an MOT emissions test, so it is for off-road and competition use only.
Do I need a remap?
A suitable remap is strongly recommended, as the engine management needs to account for the change in flow and sensor readings. Speak to your tuner before fitting.
Can I use it with my standard exhaust?
It depends on the version. Some are made for the factory (OE) system and others for the Milltek cat-back, so check the notes for the option you choose.
Will removing the cat cause a warning light?
Without suitable software it is likely to, as the ECU expects the readings a working catalyst gives. This is why Milltek pairs it with a remap.
How long does it take to fit?
Milltek quotes approx. 2 to 2.5 hours.
What is it made from?
T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
Is there a warranty?
Yes. Milltek products are covered against defects in materials and workmanship. Contact us with your order number if you have a problem.
