The Aston Martin DB11 V12 5.2 exhaust in detail.
The most frequent regret of DB11 V12 owners fits into one sentence: the 5.2-litre twin-turbo is majestic, but it has less voice than the naturally aspirated V12s that came before. Forced induction and regulations have softened the tone of an engine that nonetheless offers aeroplane-like torque and endless top-end reach.
The system is for the 2017 to 2019 DB11 V12, in both its specifications: 608 hp for the original version, 639 hp for the AMR, both with 700 Nm. The DB11 with the 4.0 V8 engine has a separate page, with its own system. We build to your VIN, after checking compatibility.
With the valves open, the Rog valved cat-back gives the V12 back its depth: a deep presence at idle, a broad climb, harmonics restored at high revs, refined bangs on the overrun. With the valves closed, hushed cruising takes over again, as close to stock as possible. Fitting, without welding, using clamps and gaskets, takes about two hours; the factory control is retained if the DB11 has one, the Rog remote otherwise.
Under the “Manifold” option, the page actually offers the downpipe, the part that follows the turbos and contains the catalytic converter. Without an ECU remap, replacing it affects sound and weight; for power, an ECU remap is essential, and the published Stage 2 figures for the 639 hp version reach 766 hp and 945 Nm. On the twin-turbo twelve-cylinder, a 200-cell downpipe keeps emissions control, a 100-cell one is accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use, far from a DB11’s primary calling. 304 stainless steel for roundness, titanium for its roughly 40% weight saving and its brushed, gold or purple finishes: the four round outlets follow your choice.

Questions about the Aston Martin DB11 V12 5.2 exhaust.
Does the DB11 AMR take the same system as the 2017 DB11 V12?
Yes, over the period covered, from 2017 to 2019, both the 608 hp version and the 639 hp AMR share this system. We ask for the VIN with the order to confirm it on your car before starting manufacturing.
Does the DB11’s V12 5.2 need an ECU remap after fitting the system?
The cat-back alone does without one: the V12 keeps its factory map. An ECU remap at an approved tuning centre makes sense with the downpipe; that is how the 639 hp version reaches the 766 hp published for Stage 2.
Aston Martin DB11 V12 5.2 with a Rog exhaust: what should you know about vehicle inspection?
Present it with the valves closed, and it returns to a sound close to standard. With the factory front section or the 200-cell downpipe, the twin-turbo’s catalytic converters stay active. The 100-cell is assessed according to the vehicle and the country; the decat version does not leave the track.
On the DB11 V12, who decides when the valves open?
With factory valves, the Aston’s drive modes are in charge, as before. Without them, the Rog remote: a single touch is enough, from inside the cabin or outside, whatever the selected mode.
Aston Martin DB11 V12 5.2: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear muffler and the cabin stays calm at a steady speed. Our Rog exhausts are designed to avoid drone. Learn more: Why our systems stay calm on the highway.
