This stainless steel downpipe reduces the back pressure of the 4.0 V8 biturbo in your Mercedes-AMG G63 W463A for faster response and a more powerful sound.

The downpipe is made of T304 stainless steel and fully TIG-welded for optimal flow and robust strength. The minimally restrictive design ensures faster turbo spool and a dominant V8 sound. Choose catless or a high-flow sports catalytic converter, each with or without heat shield.

Features

T304 stainless steel: durable and heat-resistant, fully TIG-welded
Less back pressure: faster turbo spool and more power
Catless or high-flow sports cat: choose the configuration that suits your setup
Heat shield optional: every version is available with or without heat shield
OEM+ fitment: direct installation without modifications to the chassis or exhaust system

Compatibility

Mercedes-AMG G63 W463A and W464 4.0 V8 biturbo (2018+)

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.
