The Mercedes-Benz GLE450 W167 exhaust in detail.
On a large SUV like the GLE450 W167, the M256 inline-six plays the smoothness card: 3.0 litres, turbo, 367 hp and 500 Nm available very early, delivered through 4MATIC. The inline layout, naturally balanced, runs with remarkable regularity. This page covers the 2020 to 2022 model years, not 2019; the GLE53 AMG and the GLE63 from the same family have their own pages.
Its note is smooth and continuous, recognizable among all others, and gains body under acceleration; in the standard GLE450, it never gets beyond a murmur, covered by careful sound insulation and bulky mufflers. With the valves open, the Rog cat-back gives it a rounder bass at idle and a more present climb; with them closed, the SUV stays serene on long transit runs.
The system, built for your VIN, attaches in about two hours with clamps and gaskets, without welding. The valves stay on the factory control if the GLE has one; otherwise, the two-button Rog remote opens and closes them.
According to specialist manufacturers, the downpipe sold under the “Manifold” option is the same as the one on the GLE53 W167, the first generation of the M256. Fitted in 200-cell form, it keeps the emissions control of a family SUV. More open, the 100-cell version, accepted or not depending on the car and the rules in your country, and the decat variant, reserved for track use, hardly suit the way a GLE450 is used. For this M256, the page gives no Stage 2 figure. 304 stainless steel is offered, as is titanium, around 40% lighter.

Questions about the Mercedes-Benz GLE450 W167 3.0 turbo exhaust.
My GLE450 W167 is a 2019 model: can I order this system?
Our page excludes 2019 and lists the 2020 to 2022 GLE450 W167. Depending on the exact production date, the VIN lets us decide; we always check before building.
Does the M256 in a modified GLE450 W167 need an ECU remap?
Not for the cat-back, which the GLE450’s electronic management accepts without adjustment. For the downpipe, only an ECU remap converts the flow into power; the page publishes no Stage 2 figure for this version.
Vehicle inspection and a modified GLE450 W167: which options should be kept?
The cat-back alone or a 200-cell downpipe, with the valves closed for the inspection: factory sound, active emissions control. Fitted with a 100-cell downpipe, the GLE450 will be accepted or not depending on the vehicle and your country’s rules, and it is up to the inspector to judge. Reserved for track use, the decat variant is not presented.
Do long highway journeys stay relaxing on board a modified GLE450 W167?
Yes: the gases pass through the muffler as long as the valves are closed, and the six-cylinder fades into the background. You only hear it when you choose to open them.
Can the GLE450 Coupé C167 take this system?
Yes, where it is sold: the GLE450 Coupé C167, offered in some markets outside Europe, takes the same system as the W167 SUV, like the GLE 53 and GLE 63 Coupés. Your VIN confirms the version before manufacturing.
Mercedes-Benz GLE450 W167 3.0 turbo: 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.
