Bentley Flying Spur V8 ZG2: a limousine that knows how to growl, the exhaust guide
The Flying Spur is Bentley's large sedan, built to eat up the miles in drawing-room silence. In V8 form, it relies on a 4.0-liter twin-turbo with no shortage of torque or character, but which the factory exhaust deliberately keeps muted. The following chapters guide you through each choice, material, valves and fitting, without compromising the car's refinement.
Your valved exhaust for Bentley Flying Spur V8 is configured from your VIN, and the Bentley Valved Exhaust page brings together all our Bentley systems.

The 4.0-liter twin-turbo V8: the serene power of the Flying Spur
The Flying Spur ZG2 V8 is built around a 4.0-liter V8 boosted by two turbos, nestled in the vee of the engine to shorten the gas path and make the response more direct. It delivers 550 hp and 770 Nm, a considerable torque figure that arrives very early and moves this large sedan with disconcerting ease. In everyday driving, that means effortless overtaking with the pedal barely pressed.
The factory exhaust was designed to keep the cabin quiet, and it succeeds by smothering almost all of the V8's voice. Fitted in its place with no remap and no work on the engine, the Rog valved exhaust does not turn the Flying Spur into a noisy racing car: it lets you choose between the calm of a limousine and the presence of a big V8, depending on the road and your mood.
What makes up the exhaust on your Bentley Flying Spur V8 ZG2
An exhaust system is best understood in two parts. Here is what each one does, and what Rog replaces.
The cat-back is the complete exhaust system
It is everything you can see under your Bentley Flying Spur V8 ZG2, from the outlet of the front section to the tips: pipes, muffler, valves. This is the part where most of our research and development goes: it is what shapes the sound, and it is enough on its own to transform the car.
The front section, where the catalytic converter sits
On your Bentley Flying Spur V8 ZG2, it is the downpipe, the pipe leading from the turbo. It contains the factory catalytic converter: the second restriction in the exhaust, after the muffler. Replacing it is optional: it frees up the flow, and it is the ECU remap that turns that into horsepower.
Your Bentley Flying Spur V8 ZG2 in figures
An exhaust system is judged first by ear and on the scales. The extra horsepower comes from an ECU remap.

The Rog exhaust works with or without an ECU remap. To get the full potential out of your Bentley Flying Spur V8 ZG2, we advise taking it to an approved tuning center afterwards.
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
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 safe bet: strong, corrosion-proof, with a full, rounded sound. The best value for money.
Titanium
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
It makes the exhaust around 40% lighter for the same design. Its note is more metallic and clearer higher up the rev range, and its finish ranges from brushed to blued.
No worries on durability: 304 stainless steel shrugs off winter road salt and titanium does not rust. Stainless steel or titanium: what really changes.
-
Step 2 of 3: Front section: downpipe and catalytic converter
Optional: the downpipe on your Bentley Flying Spur V8 ZG2, with its catalytic converter. Each option is placed on our sound scale of 0 to 10, valves open, with the factory exhaust at 3.
Cat-back only
Included
7/10Factory emissions control
The factory front section stays in place. It is already a complete transformation, and the choice of many of our customers.
200-cell sports catalytic converter
8/10Road use and inspection
More flow, emissions control retained: the right option for road use.
100-cell sports catalytic converter
9/10Inspection: depends on local rules
More open than the 200-cell: the sound hardens at high revs and emissions control is reduced.
Decat
10/10Track use
Flow with no filter at all: the rawest sound and the sharpest response.
Sound intensity, on a scale of 0 to 10
- 10/10Decat downpipe + Rog cat-back
- 9/10100-cell sports catalytic converter + Rog cat-back
- 8/10200-cell sports catalytic converter + Rog cat-back
- 7/10Rog cat-back only, factory catalytic converter retained
- 3/10Factory exhaust, for comparison
Valves open. With the valves closed, every configuration becomes discreet again.
What about the engine warning light? With a sports cat, it can come on with some engines: the sensor placed after the catalytic converter measures a different level of emissions control from the original. It is not a mechanical failure, but a warning light should never be masked or cleared without dealing with its cause: the right answer is a catalytic converter suited to the engine, with a map by a tuner who takes it into account. The decat version, for track use only, almost always triggers it. If this happens to you, write to us and we will point you in the right direction. Passing vehicle inspection with a sports exhaust.
-
Step 3 of 3: Valves: Rog remote or factory control
Two ways to control the valves on your Bentley Flying Spur V8 ZG2.
Rog remote
A discreet control unit in the trunk and a two-button remote: you open and close whenever you like, independently of the drive modes. For fitting, we support you by email.
Factory control
- Only for vehicles fitted with factory valves
- Controlled by the drive modes
For vehicles fitted with factory valves: the exhaust connects to their control and the drive modes stay in charge, with no extra control unit.
At 130 km/h, many sports exhausts drone. Here, with the valves closed, the exhaust flows through the muffler and stays composed when cruising; open, it makes itself heard when you choose. 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 V8 of the Flying Spur
A twin-turbo V8 of this displacement naturally has a deep, low voice, with the characteristic burble of a V8 at idle. In the Flying Spur, the factory exhaust reduces it to a distant murmur, more sensed than heard, even under hard acceleration.
With the valves open, the Rog exhaust releases that rumble: a more assertive start-up, overtaking you can hear, and a rich sound that stays noble rather than aggressive. With the valves closed, the Flying Spur becomes a drawing room on wheels again, for long journeys or a discreet arrival at a hotel.

Every Bentley Flying Spur V8 ZG2 has its own story and its own use: if none of these profiles sounds like you, let's talk.
Bentley Flying Spur V8 ZG2: your questions
How much power does an exhaust add on the Bentley Flying Spur V8 ZG2?
As standard, the Bentley Flying Spur V8 ZG2 produces 550 hp and 770 Nm. The exhaust alone acts first on sound, breathing and weight; the extra horsepower comes from an ECU remap.
Stainless steel or titanium: which material for the Bentley Flying Spur V8 ZG2?
The Rog exhaust comes in stainless steel and titanium, at the price shown on the product page in your currency. Stainless steel is the safe bet, with a full sound; titanium makes the exhaust around 40% lighter and gives a more metallic note higher up the rev range.
Do you need to replace the catalytic converter on the Bentley Flying Spur V8 ZG2?
It is not compulsory. The cat-back alone is enough to change the character of the Bentley Flying Spur V8 ZG2. Replacing the downpipe is how you go further, together with an ECU remap: 200 cells for the road, 100 cells or decat for more radical use.
Will a Rog exhaust pass vehicle inspection on the Bentley Flying Spur V8 ZG2?
The cat-back only and the 200-cell converter both retain emissions control: present the Bentley Flying Spur V8 ZG2 with the valves closed. With the 100-cell, acceptance at the emissions test depends on the car and local rules; the decat is intended for track use.
How is the Rog exhaust fitted on the Bentley Flying Spur V8 ZG2?
With clamps and gaskets, no welding or cutting: around two hours in the workshop for a well-equipped mechanic. The exhaust is built to the VIN of your Bentley Flying Spur V8 ZG2.
What price and lead time for a Rog exhaust on the Bentley Flying Spur V8 ZG2?
The price depends on the configuration and is shown on the product page, in your currency. Allow 20 working days from order confirmation to delivery. Delivery is free and the exhaust comes with a 3-year warranty.
