Milltek Large-bore Downpipe & Sports Cat for Mercedes A-Class A35 AMG 2.0 Turbo (Saloon/Sedan Only - Non OPF/GPF Models) (2019 onwards) – Improved Flow, Sports Catalyst
This is Milltek's large-bore downpipe with hi-flow sports cat for the Mercedes A-Class A35 AMG 2.0 Turbo (Saloon/Sedan Only - OPF/GPF Models). It replaces the restrictive factory downpipe with a larger-bore pipe fitted with a high-flow sports catalyst in place of the standard unit, using a less dense substrate that flows significantly better than the factory cat while still treating the exhaust gases passing through it.
It sits between a stock downpipe and a full de-cat: a genuine flow gain suited to a Stage 1 or Stage 2 remap, without giving up the catalyst entirely the way a de-cat pipe does.
In the UK, a replacement catalyst on a car first registered from 1 March 2001 needs ECE R103 type-approval to be road legal, so check the EC Approved line in the specification for the version you choose.

Installation
Milltek quotes a fitting time of approx. 2.5 to 3.5 hours. Before ordering, note: Fits with Milltek Sport GPF/OPF Bypass - Requires Stage 2 ECU Remap. This work involves removing parts close to the turbo and engine, so we recommend fitting by a specialist with a ramp and suitable software support.

Will it fit the Mercedes A-Class A35 AMG 2.0 Turbo (Saloon/Sedan Only - OPF/GPF Models)?
Yes. Milltek lists this part for the Mercedes A-Class A35 AMG 2.0 Turbo (Saloon/Sedan Only - OPF/GPF Models) as well as the other models in the fitment list above.
Is it road legal?
Milltek lists this as a race part without EC approval, so it is intended for off-road and competition use.
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.
How is a sports cat different from a de-cat?
A sports cat still contains a catalyst, just a less dense one that flows better than the factory unit. A de-cat removes the catalyst completely.
How long does it take to fit?
Milltek quotes approx. 2.5 to 3.5 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.
