Audi RS7 4G 4.0 TFSI V8 Valved Exhaust System (2013-2018)

The Audi RS7 4G exhaust in detail.

Under the internal code 4G, the first RS7 Sportback, from 2013 to 2018, shares with the RS6 Avant of the same period the 4.0 TFSI, a twin-turbo V8 with its turbos housed in the vee, rated here at 560 hp and 700 Nm. The RS6 Avant C7 has its own page, established for the wagon alone, and so does the more recent RS7 C8.

Massive torque, instant response, and a sound the factory exhaust keeps too discreet: between the hot-vee turbo layout and mufflers designed for cruising, this V8 murmurs where it could rumble. With the valves open, our valved cat-back releases its pulse, deep at idle, authoritative when accelerating; with the valves closed, the five-door coupé becomes a hushed grand tourer again.

The RS6 Avant C7 system does not fit the RS7, whose rear section is specific to the Sportback: we check your VIN before any manufacturing. On a lift, about two hours is enough, without welding; the RS7 keeps controlling its valves through the drive modes, and the Rog remote is only used when there are no factory valves.

Under the “Manifold” label, the page actually sells the V8’s two downpipes, catalytic converters included. A five-door coupé of this size often serves as an everyday car: the 200-cell versions, which keep emissions control, suit it, while the 100-cell versions are accepted or not depending on the car and the rules in your country and the decat versions are reserved for track use. Without a modified map, the 560 hp stays untouched. 304 stainless steel for a full bass note, titanium around 40% lighter in three colors.
