Valve‑controlled performance catback for Audi 8V RS3 Sportback 2.5 five‑cylinder 2016 onward

Unlock the iconic five‑pot tone and sharper throttle feel with this premium Austrian‑built catback. Designed as a direct replacement from the catalytic converter back, it integrates with the factory valve control for civilised motorway manners and a fierce, motorsport‑inspired soundtrack when you want it. Precision‑made from stainless steel with a shot‑blasted finish, the 76 mm tubing and quad 84 mm outlets deliver freer flow, reduced back pressure and a perfect fit on the 8VA Sportback platform.

We have installed this system on customer cars and our own demonstrators at MJ Modifications, and the feedback is consistently outstanding on tone, build quality and fitment. If you are searching for an RS3 exhaust upgrade that keeps comfort while adding drama, this is the one.

How it drives

The free‑flow layout lowers back pressure for crisper response and a more engaging drive. With the valves closed you get a refined, low‑drone cruise. Open them and the legendary five‑cylinder character comes alive with a deep, hard‑edged note that sounds superb on throttle yet remains tidy at steady speeds.
