The Mercedes-Benz G550 W463A exhaust in detail.
The G550 W463A, the renewed generation of the G-Class, gets a 4.0-litre V8 with its two turbos housed in the vee: 422 hp and 610 Nm, abundant torque from low revs to move this off-roader with ease. With all-wheel drive and the three differential locks that made the G’s reputation, it is as at home on the highway as off-road, for the 2021 to 2024 model years covered here.
Deep and round, with the irregular idle rumble typical of V8s, this engine is reduced by the factory exhaust to background noise out of all proportion to the vehicle’s stature. The Rog cat-back, valves open, makes it rumble at start-up and build under acceleration; with the valves closed, the G550 becomes discreet again, in town as on country lanes.
This vehicle is also designated W464, which we link to the W463A in our catalogue; for the front section, only the G550 is named, not the G500, hence a VIN check. The valved system fits in about two hours, with clamps and gaskets, no welding; original valve control retained, or the Rog remote.
For this V8 with central turbos, the part sold under the “Manifold” option is the catalyzed downpipe. The 200-cell version keeps emissions control, sufficient for road use. The 100-cell will be accepted or not depending on the vehicle and your country’s rules; reserved for track use, the decat variant has no place on an off-roader of this kind. No Stage 2 figure is published for the G550; only an ECU remap would turn the part into horsepower. 304 stainless steel stands up to winter road salt; titanium, around 40% lighter, adds a finish of your choice.

Questions about the Mercedes-Benz G550 W463A 4.0 V8 biturbo exhaust.
My G-Class is a European G500 W463A: is the G550 system meant for it?
Our page lists the system for both the G500 and the G550, but the front part only names the G550. Send us your G500’s VIN: we check before manufacturing, especially if you want the downpipe.
Is an ECU remap needed on a G550 W463A fitted with the cat-back?
No, the cat-back requires no work on the map. With the downpipe, an ECU remap becomes useful to get power out of it; the page publishes no Stage 2 for this G550.
Mercedes-Benz G550 W463A 4.0 V8 biturbo with a Rog exhaust: what should you know about vehicle inspection?
Presented with the valves closed, with the cat-back alone or the 200-cell downpipe, it keeps its emissions control and a factory volume. Fitted with a 100-cell downpipe, the G550 will be accepted or not depending on the vehicle and your country’s rules. As for the decat variant, reserved for track use, it is unthinkable on a registered G-Class.
Does the G550 W463A stay discreet in town with the system?
Yes, with the valves closed: the V8 becomes background noise again, just as on delivery. The rumble only returns when you open them, on the road or for a start-up.
Mercedes-Benz G550 W463A 4.0 V8 biturbo: 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.
