Aston Martin DB12: unleashing the twin-turbo V8, the complete exhaust system guide
The DB12 opens the era of the Super Tourer: 680 hp of twin-turbo V8 and complete technological refinement.

Here, point by point, is how to choose the exhaust for your Aston Martin DB12 V8, and what each option really changes.

The 4.0 twin-turbo V8: AMG at heart, set to music by Aston Martin
The twin-turbo 4.0 V8 in your DB12 comes from Affalterbach, but Aston Martin has completely retuned it: intake, engine management and above all an exhaust unique to Gaydon. The factory result is already expressive, but recent regulations have imposed their filters, and part of the character stays locked away. On an Aston, the sound is part of the emotional brief: it deserves to be complete.
The ROG exhaust unleashes this V8 completely: a deep rumble, an authoritative climb, and refined bangs on the overrun. And the valves preserve the hushed elegance that is also part of the brand's charm.
How the exhaust on your Aston Martin DB12 V8 is put together
Here is what the ROG exhaust replaces, and where the sound is shaped.
The cat-back is the complete exhaust system
It is everything you can see under your Aston Martin DB12 V8, all the way to the tips: pipes, silencer, valves. Routing, silencer, valves: this is where the sound is shaped. The engine and the ECU stay as they left the factory.
Your Aston Martin DB12 V8 in figures
What an exhaust changes straight away is the sound, the engine's breathing and the weight at the rear. For more power, add an ECU remap.
Power
Torque
Published factory and Stage 2 figures.
With or without an ECU remap, the exhaust fits and works. But it is an ECU remap at an approved tuning centre that truly unleashes your Aston Martin DB12 V8, and that is what we recommend.
To be completely transparent: the exhaust alone brings better breathing and sound, while Stage 2 brings the transformation. The 4.0 twin-turbo V8 is proven and well documented: with an ECU remap at an approved tuning centre, the figures above stay within the reliability range of an engine designed with headroom.
Configuring your exhaust, step by step
3 choices, in the same order as the product page configurator.
-
Step 1 of 3: Material: stainless steel or titanium
For your Aston Martin DB12 V8, the exhaust costs €5,490 in stainless steel and €6,490 in titanium.
304 stainless steel
5 490 €
- Weight
- Baseline
- Sound
- Full and rounded
Durable, corrosion-resistant, with a rounded, full sound: the most popular option.
Titanium
6 490 €
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
For the same design, it weighs around 40% less than stainless steel. A more metallic note at high revs and a look all of its own, from brushed to blued.
Both materials age well: 304 stainless steel copes with winter and salt, and titanium does not rust. Stainless steel or titanium: what really changes.
-
Step 2 of 3: Valves: ROG remote or factory control
Two ways to control the valves on your Aston Martin DB12 V8.
ROG remote
The simplest solution: a control unit in the boot and a remote, open or closed at the press of a button, whatever mode you are in. A question while fitting? We will get back to you.
Factory control
- Only for vehicles fitted with factory valves
- Controlled by the drive modes
Does your vehicle have factory valves? The exhaust keeps their existing control: the drive modes operate the valves, as before, with no added electronics.
On a long journey, what matters is the absence of drone at a steady speed. With the valves closed, the exhaust keeps the cabin calm; the show is still there whenever you ask for it. More about exhaust drone.

The ROG sound signature on the Aston V8
Our exhaust unleashes the V8's full character: a deep rumble at idle, an authoritative, refined climb, and crisp bangs on the overrun with the valves open. With the valves closed, the hushed grand touring elegance is fully preserved. An Aston should be able to do both: ours does.
