The Bentley Continental GT / GTC W12 exhaust (2019 to 2024) in detail.
Twelve cylinders in a W, locomotive torque, absolute refinement: the third Continental GT pushes its 6.0-litre twin-turbo W12 to 635 hp and 900 Nm, for the 2019 to 2024 model years covered by this page. The page targets the GT coupé and the GTC convertible. The Continental GT V8 and the W12s of earlier generations each have their own page.
Bentley tuned this engine for cathedral-like silence, true to the spirit of Crewe, while a growing number of owners want to be able to hear it, at least when they choose to. With the valves open, the Rog valved cat-back reveals a deep, velvety rumble, as unique as its architecture, punctuated by muffled bangs on the overrun. With the valves closed, the calm of the cabin is fully preserved.
Weld-free fitting: clamps, gaskets and about two hours for an equipped workshop. Factory valves stay controlled by the car; failing that, the Rog remote, with its box in the boot and two buttons, takes care of it.
The page also sells the “Manifold” option, meaning the downpipes fitted under the turbos with the catalytic converters, although this part is not yet documented in our records for the W12: we check it against your VIN before manufacturing. If it is confirmed for your car, choose the 200-cell version, the only one that keeps the emissions control of a long-distance coupé; in 100-cell form, it is accepted or not depending on the vehicle and your country’s rules, and its decat variant is reserved for track use. As for materials, 304 stainless steel suits the W12’s deep tone, while titanium saves around 40% of the weight and takes a brushed, gold or purple finish.

Questions about the Bentley Continental GT / GTC W12 6.0 exhaust.
Does the recent GTC W12 convertible fall within this page?
Yes. The third-generation GT coupé and GTC W12 convertible take the same Rog system: same chassis, same W12, same clamp-and-gasket fitting. Your VIN is only used to confirm the version and model year before manufacturing.
How much horsepower does a 635 hp Continental GT W12 gain in Stage 2?
We do not display it: the cat-back works with the original engine management, and the Stage 2 figures noted for this W12 do not match between the page and the guide.
How should a recent Continental GT W12 be presented at vehicle inspection?
With the valves closed, the W12 regains its stock silence. Exhaust gas treatment stays as it was from the factory with the cat-back alone or 200-cell downpipes. The 100-cell parts depend on the vehicle and your country’s rules, and the version without a catalytic converter is for the circuit only.
How long between ordering and fitting on a recent Continental GT W12?
The system is built for your car after checking the VIN, then delivered free of charge: 20 working days from confirmation to delivery. Fitting then takes about two hours.
Bentley Continental GT / GTC W12 6.0: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear silencer 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 motorway.
