This stainless steel downpipe improves the flow, response and sound of the 2.5 TFSI five-cylinder in your Audi RS3 8Y.

The downpipe replaces the restrictive OEM catalytic converter for faster turbo spool and better response, with the raw five-cylinder sound as a result. It is made of T304 stainless steel, fully TIG-welded, and can be combined with Stage 1 and Stage 2 tuning. Available as catless or with high flow sports catalytic converter, both with or without heat shield.

Please note: the catless version is intended for off-road use and does not meet the emission requirements for use on public roads.

Features

Maximum flow: faster turbo spool and better response.
Five-cylinder sound: raw, sporty tone.
T304 stainless steel: fully TIG-welded, resistant to extreme temperatures.
Optional heat shield: for thermal efficiency and protection of surrounding components.
Tuning-ready: can be combined with Stage 1 and Stage 2.

Compatibility

Audi RS3 8Y (2021+), Sportback and Sedan

ABOUT US

TOWMA was born out of pure passion. Not because it was a smart business opportunity, but because cars have always shaped a big part of our lives. It started with long evenings in the garage, endless searching for the right parts and the feeling that in Europe there were simply too few truly high-quality options available. Too often we saw products that looked good in photos but in reality disappointed in quality, fitment and finish. That had to change.

What drives us is an obsession with perfection. The right lines, the right material, the right sound. We believe a car is more than transport. It is emotion. It is character. It is an extension of who you are. That is why we only select products we fully stand behind ourselves. No compromises, no mass production, no quick profit. Only parts we would install ourselves.

TOWMA is built on trust, transparency and long-term relationships. We do not want quick sales, but customers who come back because they know they get quality and honest advice here. Every order, every point of contact and every product contributes to that goal.

We understand the passion of our customers, because we feel that same passion every day. That is the reason TOWMA exists. Not to become the biggest, but to be the best choice for enthusiasts who settle for nothing less than the highest level.

OUR BUILD

Real owners. Real fitment.
