Aston Martin DBS Superleggera / Volante V12 Valved Exhaust System (2018-2024)

The Aston Martin DBS Superleggera / Volante V12 exhaust in detail.

The DBS Superleggera places the 5.2-litre twin-turbo V12 at the top of the modern range: 725 hp, 900 Nm, jet-like torque and majestic reach, in a grand touring package built from 2018 to 2024. Yet forced induction and emissions standards have softened its voice compared with the naturally aspirated V12s of old, and that is the regret its owners express most often.

The Rog valved cat-back, also known as a valve exhaust, answers exactly this regret: with the valves open, it unleashes the V12’s depth and harmonics, a deep presence at idle and a broad climb, punctuated by thoroughbred bangs on the overrun, then the grand tourer becomes hushed again as soon as the valves close. The DB11 V12, which shares this engine’s architecture, has its own page, and your VIN is checked before manufacturing.

Under a car of this standing, the exhaust fits without welding, with clamps and gaskets, in about two hours; the factory valve control is retained if there is one, otherwise the Rog remote decides.

After the V12’s turbos, the front section carrying the catalytic converter is a downpipe, which this page replaces under the “Manifold” option. On a Superleggera without a remap, it affects sound and weight; it is the map that turns that flow into power, depending on the tune. Because a Superleggera lives mainly on the road, the 200-cell version, which keeps emissions control, is the most coherent choice; the 100-cell will depend on the vehicle and your country’s rules, and the decat version is intended for track use only. Titanium, around 40% lighter than 304 stainless steel for the same design, echoes the car’s name.
