Audi RS3 8V 2.5 TFSI Valved Exhaust System (2016-2020)

Which valved exhaust for an Audi RS3 8V?

The Rog system for the Audi RS3 8V is a valved cat-back exhaust in 304 stainless steel or titanium, built to your VIN for the 2.5 TFSI five-cylinder with 367 hp, then 400 hp from 2017. Valves open, the 1-2-4-5-3 rhythm of the rally quattros comes back in full; valves closed, the RS3 remains a compact you can live with every day.

Sound, options and fitting in detail: our Audi RS3 8V guide.

Two power outputs share this page: the pre-facelift RS3 8V, at 367 hp and 465 Nm, then the facelifted version raised to 400 hp and 480 Nm. From 2016 to 2020, both use the 2.5 TFSI, a turbocharged inline-five. Our data does not distinguish between body style or phase, so your VIN settles the question before manufacturing. The RS3 8Y that succeeded it has its own page.

This engine owes its reputation to a cadence you can recognise with your eyes closed: the 1-2-4-5-3 firing order gives an odd rhythm, between rumble and howl, that recalls Audi’s quattro rally cars. Filters and silencers imposed by regulations erase most of it. With the valves open, this valved cat-back gives the five-cylinder back its gust under acceleration and its rich crackles; with the valves closed, the hatchback regains almost well-behaved manners.

The page also sells the “Manifold” option, which on this engine corresponds to the downpipe: it is the part that carries the catalytic converter at the turbo outlet. If the RS3 stays registered and driven on public roads, the 200-cell catalysed downpipe is the one that keeps emissions control in place; the 100-cell is accepted or not depending on the vehicle and your country’s rules, while the decat version is reserved for track use and track days. On its own, without a revised map, this part does not change the RS3’s power: it adds sound and saves a little weight.

No welding to install it: clamps, gaskets, about two hours, and round tailpipes that replace the factory ones. The Audi drive modes control the valves if the car has them from the factory, otherwise the Rog remote takes over. As for materials, 304 stainless steel serves the five-cylinder’s full voice, and titanium, around 40% lighter, adds a metallic sparkle, in brushed, gold or purple.
