Milltek Cat-back Exhaust for Audi A3 2.0T FSI 2WD 3 door (2003-2012) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Seat Leon FR 2.0 T FSI 200-211PS. 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 Seat Leon Cupra 2.0T FSI 240PS?
Yes. Milltek lists this part for the Seat Leon Cupra 2.0T FSI 240PS as well as the other models in the fitment list above.
Does it fit the Audi A3 2.0T FSI 2WD 5 door Sportback?
No. For that car, choose the Milltek Cat-back Exhaust Audi A3 2.0T FSI 2WD 5dr Sportback 03-12.
Is it road legal?
Every version of this part is listed by Milltek as EC approved.
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?

What is it made from?
