Best valved exhaust for Mercedes-AMG C63 and C63 S W205 / S205

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: Mercedes C-Class W205 Valved Exhaust.

The W205 C63 holds a special place in AMG's history: it is the last C-Class to receive a V8. Sedan or wagon, C63 or C63 S, it combines the dimensions of an everyday car with the engine of a great sports car. Before configuring its exhaust, here is what defines it.

The last V8-engined C-Class

Mercedes-AMG presented the W205-generation C63 at the Paris Motor Show on 2 October 2014. The C63 S sedan opened sales in February 2015, and the other versions, the S205 wagon included, followed in spring. The C205 coupé and the A205 convertible came to complete the family later, with widened tracks and a rear end of their own.

In spring 2018, the range was facelifted and presented at the New York Auto Show, for sale from September. Panamericana grille, revised diffuser, new transmission and new driving modes: the C63 modernized itself without touching its V8. The next generation, the W206, opted for a hybrid four-cylinder: the W205 will therefore remain the last eight-cylinder C63.

Our product page targets the W205 sedan and the S205 wagon, from 2015 to 2020, before and after the facelift. A 2021 car, a coupé or a convertible? Send us its VIN first: we check what we can make and reply in writing within 24 hours.

C63 or C63 S: two power levels

The C63 is quoted at 476 hp, or 350 kW, and 650 Nm. The C63 S rises to 510 hp, or 375 kW, and 700 Nm. At launch, Mercedes-AMG quoted 4.1 seconds to take the C63 sedan to 100 km/h, and 4.0 seconds for the C63 S; as a wagon, each version concedes a tenth. Both versions kept these outputs after the 2018 facelift.

Beyond power, the S was distinguished at launch by an electronically controlled limited-slip rear differential, where the C63 received a mechanical autolocking one, and by a Race driving mode reserved for it. For the exhaust, these differences do not matter: C63 and C63 S, sedan or wagon, share the same Rog exhaust.

Right after this you will find the factory figures of each version, as our product page publishes them.

Stage 2: published figures with the front section and an ECU remap carried out by a tuner.

The twin-turbo V8 with turbos in the V

Under the hood of the C63, a 3,982 cc V8 whose two turbochargers are housed between the cylinder banks, in the V. Mercedes-AMG speaks of a "hot V": the exhaust gases leave inside the V, which shortens their path to the turbines and makes the response sharper. Direct injection with piezo injectors completes the package.

For the exhaust, this architecture has a direct consequence: each turbo has its own downpipe, which carries its catalytic converter. These two downpipes form the front section. The cat-back follows them and heads to the rear of the sedan or wagon, where it ends in four outlets; it is what carries the mufflers and the valves.

Seven, then nine speeds

Until 2018, the W205 C63 uses the seven-speed AMG Speedshift MCT transmission, with steering-wheel paddles. The facelift replaced it with a nine-speed MCT, also operable with the paddles. All facelifted C63s also receive the electronically controlled rear differential.

Our product page makes no difference between the two transmissions: a 2016 C63 and a 2019 C63 S receive the same Rog cat-back. What does change is how the car manages its valves according to the driving modes, which we detail below.

The rumble of the AMG V8

The AMG V8 has one of the most recognizable sounds in the motoring world: a deep, rolling rumble at idle, a rise in revs that sounds like thunder, and dry detonations when you lift off the accelerator. Mercedes-AMG made it a development objective in its own right, with a sound that was meant to evoke that of a touring-car racer in the sportiest modes.

Placed at the heart of the V, the two turbos nevertheless damp the pulses of the gases well before the exhaust, and the factory muffler finishes smoothing them. With the Rog exhaust, valves open, the V8 regains its full rumble, from outside as from the cabin; with the valves closed, the C63 resumes the manners of a big sedan, to cross a town early in the morning or rack up hours of highway.

The standard valves and the AMG modes

As standard, the C63 and C63 S have a sport exhaust with a valve, which the car opens according to the driving program, the accelerator and the engine speed. As an option, the Performance exhaust had three switchable valves, with an even more marked sound from one mode to the next. The modes themselves have evolved: Controlled Efficiency, Sport, Sport Plus and Individual at launch, plus Race for the S; after the facelift, from Slippery to Race depending on the version.

In the calmest programs, the car favors the route through the bulky factory mufflers, which hold the V8 back. It is this compromise that the Rog exhaust modifies, without taking away the car's ability to drive in silence.

Your AMG modes or the Rog remote

The product page offers two systems. Choose Factory, and we provide on the exhaust the mounting points for your C63's valves: your garage puts the car's valves back there, and the AMG programs carry on deciding. The VIN tells us whether the car left the factory with the sport exhaust or the Performance exhaust, and we take that into account before manufacture.

Choose Rog, and the exhaust reaches you with our own valves, already fitted, a small remote and a control unit for the trunk. Once open, they do not close again by themselves, even in Comfort; once closed, they no longer move, even in Race. On a car as versatile as a C63 wagon, it is the simplest way to choose your voice at every moment.

Front section, material and what the product page does not do

On the product page, the "Manifold" option replaces the two downpipes of the V8. Three versions are offered: 200-cell sport catalytic converters, with emissions control that stays in place; 100-cell catalytic converters, whose acceptance depends on the car and the country; or downpipes without catalytic converters, for the track only. A C63 that is driven all year round will be well served by the 200-cell.

As long as AMG's mapping stays in place, the Rog exhaust acts on the sound and not on the power. To gain horsepower, the downpipes must be replaced and the engine entrusted to a tuner for a new mapping. As for material, 304 stainless steel stands up to the winters and gives the V8 a full voice; titanium takes about 40% off the weight for an identical layout, and comes tinted brushed, gold or purple with no difference in price.

The C63 product page offers neither a resonator option nor a choice of tips: the exhaust is configured by its material, its front section and its valves. Rog makes it to your VIN; your garage then fits it with clamps and gaskets, without welding anything.

Configure your exhaust.

How the exhaust is put together

On the W205 C63, sedan or wagon, our cat-back takes over behind the two downpipes and extends to the four outlets: pipes, mufflers, valves. The two downpipes, each with its catalytic converter, make up the front section; the product page's "Manifold" option lets you replace them.

Each choice explained in detail, from sound to material: How to configure your exhaust.

Three recommended configurations.

• Everyday wagon

  • Stainless steel
  • No manifold
  • Factory valves

  For an S205 C63 wagon that carries the family: the factory downpipes stay in place, the V8 regains its rumble, and your AMG modes still decide when the valves open.

• Sedan with character

  • Stainless steel
  • 200-cell sports catalytic converter
  • Rog remote

  For a C63 S sedan that is driven all year round: a V8 more present in every burst of acceleration, emissions control that stays in service, and a button to silence it on arrival.

• Track days

  • Titanium
  • Catalyst-free manifold
  • Rog remote

  For a C63 S that goes on the track: catalyst-free downpipes behind the turbos, an exhaust lightened by titanium, and a V8 that sings with the valves open throughout the session.
