Milltek Cat-back Exhaust for Seat Leon Cupra 1.9 TDi 90PS/110PS/150PS (2000-2005) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Volkswagen Golf Mk4 1.9 TDI PD and non-PD. It replaces everything from the factory catalytic converter rearward with wider-bore pipework, a re-profiled mid-pipe and silencers tuned specifically for this platform, cutting back pressure and sharpening the exhaust note. The factory catalytic converter stays in place, so the car's emissions hardware is left as standard. It's offered in non-resonated or resonated versions, so you can pick the setup that suits how the car's used.
It's aimed at owners who want a noticeably different sound and a genuine, if modest, flow improvement without touching anything upstream of the cat: a straightforward bolt-on that doesn't need a remap or any other supporting mods to enjoy.

What's the difference between the resonated and non-resonated versions?
The resonated version adds extra silencing for a quieter, more refined tone. The non-resonated version leaves it out, so it is louder and more aggressive.
Will it fit the Volkswagen Golf Mk4 1.9 TDI PD and non-PD?
Yes. Milltek lists this part for the Volkswagen Golf Mk4 1.9 TDI PD and non-PD as well as the other models in the fitment list above.
Does it fit the Seat Leon Cupra R 2.0 TSI 265PS?
No. For that car, choose the Milltek Cat-back Exhaust Seat Leon Cupra R 2.0 TSI 265PS 10-12.
Is it road legal?
Milltek does not list EC approval for this part. Any exhaust used on the road must still meet noise and emissions rules, so check the requirements where you live.
Do I need a remap?
No. It fits behind the factory catalytic converter, so no software changes are needed.
Does it keep the factory catalytic converter?
Yes. It fits behind the factory catalytic converter, which stays in place.
How long does it take to fit?
It depends on the version. Milltek's fitting time for each option is shown in its specification table.
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.
