Mercedes-AMG CLS W219 Valved Exhaust System (2004-2010)

The Mercedes-AMG CLS W219 exhaust in detail.

A first-generation four-door coupé, the CLS W219 comes in an AMG version: the page credits it with 476 hp and 700 Nm, delivered by a V8 from Affalterbach’s golden era. Covered here from 2004 to 2010, it leaves the following W218 generation to another page. Your car’s VIN lets us confirm the exact version before manufacturing.

This V8 has everything that made AMG’s reputation, depth, presence and rolling thunder, but the factory exhaust keeps it too discreet for the car’s sporting nature. With the valves open, the Rog cat-back gives it back a deep rumble at idle and bangs on the overrun; with the valves closed, the W219 keeps its original cruising comfort.

Fitting in about two hours, without welding, with clamps and gaskets, on a system built for your car. It is also called a valved exhaust: the valves follow the factory control if the CLS has one, otherwise the Rog remote, whose box sits in the boot.

For this first-generation CLS, the “Manifold” option corresponds to the catalysed front section, upstream of our system. Chosen in 200-cell form, it keeps emissions control and suits a car that is still driven regularly. More open, a 100-cell version will be accepted or not depending on the vehicle and your country’s rules; the decat variant, reserved for track use, remains a rare use for a CLS of this age. Remapped with its front section, the W219 AMG reaches 546 hp and 790 Nm according to the page. As for the material, 304 stainless steel suits a CLS of this generation, while titanium lightens the system by around 40%.
