Audi A5 / A5 Avant B10 2.0 TFSI Valved Exhaust System (2025+)

The Audi A5 / A5 Avant B10 exhaust in detail.

The A5 B10 opens the 2025 generation with a 2.0 TFSI, a direct-injection turbocharged inline-four offered from 150 hp and 280 Nm up to 204 hp and 340 Nm depending on the version. The torque arrives early and carries the car effortlessly: a grand touring engine, built for flexibility. On a new car, silence is part of the brief, and the factory exhaust sticks to it.

A turbocharged four-cylinder does not have the voice of a six-cylinder, but it does have one: deep and even at idle, harder as the revs climb, with the turbo whoosh in the background. With the valves open, our valved cat-back gives it more roundness and presence; acceleration and downshifts can be heard, without excess. With the valves closed, the cabin stays calm and daily journeys are done without fatigue.

This page only offers the cat-back: there is no front section option for the A5 B10, for lack of a verified part. The engine and the ECU stay as Audi delivered them, and so does the factory emissions control. Without an ECU remap, the system changes the voice and slightly lightens the rear, not the power.

Fitting is done without welding, with clamps and gaskets, in about two hours, with round tailpipes. If the car has factory valves, the system retains their control; otherwise, the Rog remote, whose unit sits in the boot. The A5 can be ordered in 304 stainless steel, or in titanium around 40% lighter, matched to the car in brushed, gold or purple. The earlier A5 B8, B9 and 8T have their own pages.
