The 4.0 twin-turbo V8: AMG at heart, set to music by Aston Martin
The 4.0 twin-turbo V8 in your DBX707 comes from Affalterbach, but Aston Martin has completely retuned it: intake, engine management and, above all, an exhaust that is pure 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 DBX707 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 DBX707 V8, all the way to the tips: pipes, silencer, valves. This is where our research and development is focused, and it is what shapes the sound. It fits without touching the engine or the ECU.
Your Aston Martin DBX707 V8 in figures
On a modern car, an exhaust system first changes the voice, the breathing and the weight at the rear. Power, on the other hand, comes from an ECU remap.
Power
Torque
Published factory and Stage 2 figures.
Our exhaust systems work perfectly with or without an ECU remap. On your Aston Martin DBX707 V8, however, we recommend one at an approved tuning centre: it is what lets the engine deliver its full potential.
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
2 choices, in the same order as the product page configurator.
-
Step 1 of 2: Material: stainless steel or titanium
Titanium costs more than stainless steel; the price of each version is shown on the product page, in your currency.
304 stainless steel
- Weight
- Baseline
- Sound
- Full and rounded
The benchmark for high-end exhausts: tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.
Titanium
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
Around 40% lighter than stainless steel for the same design, with a more metallic sound that turns crystal-clear at high revs. Its finish ranges from brushed to blued tints.
Over time, both hold up: 304 stainless steel stands up to winter salt and damp, and titanium does not rust. Stainless steel or titanium: what really changes.
-
Step 2 of 2: Valves: Rog remote or factory control
Two ways to control the valves on your Aston Martin DBX707 V8.
Rog remote
A small control unit fits in the boot. Two buttons, open and closed: the valves respond at any moment, whatever the drive mode. Simple to fit, and we stay on hand throughout the installation.
Factory control
- Only for vehicles fitted with factory valves
- Controlled by the drive modes
If your vehicle is fitted with factory valves, the exhaust keeps their existing control. The drive modes decide, just as they did from the factory, with no added electronics.
On the motorway, with the valves closed, the gases pass through the silencer, designed for cruising: no drone at a steady speed. You open up when you feel like it, not when the motorway decides for you. More about exhaust drone.
Your choices carry over to the product page: only the finishes, your VIN and the cart remain.
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.

Aston Martin DBX707 V8: your questions
How much power does an exhaust add on the Aston Martin DBX707 V8?
As standard, the Aston Martin DBX707 V8 produces 707 hp and 900 Nm. An exhaust system on its own mainly changes the sound, the breathing and the weight; power is gained with an ECU remap. With a Stage 2 build, the published figures reach 852 hp and 1112 Nm.
Stainless steel or titanium: which material for the Aston Martin DBX707 V8?
The Rog exhaust comes in stainless steel and titanium, at the price shown on the product page in your currency. 304 stainless steel is tough, rounded in tone and the most popular choice; titanium is around 40% lighter for the same design, with a more metallic sound at high revs.
Is the Rog exhaust loud all the time on the Aston Martin DBX707 V8?
No. With the valves closed, the gases pass through the silencer and the sound stays comfortable. With the valves open, the engine speaks freely. You switch from one to the other at any moment, with the Rog remote or the factory control if your vehicle has it.
Will a Rog exhaust pass vehicle inspection on the Aston Martin DBX707 V8?
The Rog exhaust replaces the rear part of the exhaust, without touching the engine or the ECU. Present the car with the valves closed: it is the most discreet setting.
How is the Rog exhaust fitted on the Aston Martin DBX707 V8?
No welding or cutting, using clamps and gaskets. Allow two hours on average for a well-equipped mechanic. The exhaust is built for your VIN, which guarantees compatibility before it ships.
