Mercedes-AMG SL 63 R232 Valved Exhaust System (2022+)

Which valved exhaust for a Mercedes-AMG SL 63 R232?

The Rog system for the Mercedes-AMG SL 63 4MATIC+ R232 (from 2022) is a valved cat-back exhaust in 304 stainless steel or titanium, built to your VIN for the 585 hp, 800 Nm 4.0-litre twin-turbo V8. Roof down, every decibel counts: valves open, the V8 regains a deep rumble, and closed, the SL remains a grand touring roadster.

Sound, options and fitting in detail: our Mercedes-AMG SL 63 R232 guide.

At the top of the SL R232 range launched in 2022, the SL 63 AMG pushes the 4.0-litre twin-turbo V8 to 585 hp and 800 Nm, hand-assembled in Affalterbach with the turbos housed in the vee. It shares its architecture with the AMG GT C192; the less powerful SL 55 has its own page.

With the roof down, every decibel counts, and this V8, famous for its thunder, has been made polite by the particulate filter and oversized silencers. With the valves open, the Rog cat-back gives it back a deep rumble punctuated by bangs; with the valves closed, the SL 63 regains the comfort of a great touring roadster, with no fatigue on the motorway.

Built to your VIN, which also confirms the exact compatibility of such a recent model, then fitted in about two hours with clamps and gaskets, no welding. The AMG modes keep control of the factory valves; otherwise, the Rog remote.

Placed just after the turbos, the catalysed downpipe is the part this SL 63 receives under the “Manifold” option; in 200-cell form, it keeps emissions control, which suits the open-top grand tourer. The 100-cell, for its part, will be accepted or not depending on the vehicle and your country’s rules, while the decat variant is reserved for track use, far from the coastal roads an SL usually cruises. Remapped, the SL 63 rises to 740 hp and 1,000 Nm according to the page. Titanium, around 40% lighter, comes in three finishes; 304 stainless steel remains the most common choice.
