Mercedes-AMG GT63 C192 Valved Exhaust System (2024+)

The Mercedes-AMG GT63 C192 exhaust in detail.

The C192 coupé marks a break in the history of the AMG GT: AMG Performance 4MATIC+ all-wheel drive as standard for the first time, a composite aluminium body that frees up a 2+2 cabin, and an architecture shared with the SL R232. At its heart, the M177, a hand-assembled 4.0-litre twin-turbo V8 with turbos in the vee: 585 hp and 800 Nm in the GT63, from the 2024 model year onwards.

The V8 is there, but you only half hear it: the C192 generation lost in thunder what it gained in civility. The Rog cat-back, valved or with valves as some call it, gives the AMG V8 back its deep, rolling rumble and its bangs on the overrun; closed, it leaves the coupé its grand touring comfort.

On the C192, this page sells only the rear system. No front section is offered: the C192 platform uses specific downpipes that we do not list. The original catalytic converter therefore stays in place, along with emissions control, and the ECU is not touched.

Every GT63 C192 system starts from your VIN and is fitted in about two hours; clamps and gaskets are enough, no welding is done. The drive modes control the factory valves if the coupé has them; otherwise, the Rog remote. The page is for the GT63; the GT55 is not included, and the four-door GT63 X290 has its own page. As for materials, titanium saves around 40% in weight on a car already built around aluminium; 304 stainless steel remains the most common choice.
