The Milltek Sport Rear Silencer(s) are designed for the Mercedes-AMG C63 and C63 S W205 Sedan models with the 4.0-liter V8 Bi-Turbo engine without the factory-fitted GPF particulate filter. This solution replaces the rear silencers of the exhaust system and improves the sound in a controlled manner while maintaining the original character and drivability of the car.

The Rear Silencer(s) upgrade is an ideal option for the driver who wants a sportier AMG sound without replacing the entire exhaust system.

The rich and controlled sound of the AMG V8

Milltek has tuned this system to highlight the character of the V8 engine in the C63 / C63 S models:

• Deeper and fuller sound at idle

• Sporty sound as the load increases

• No annoying resonance or drone when driving on the road

The sound profile is clearly sportier than the standard system, but maintains premium comfort even on longer journeys.

Improved flow and ride feel

Milltek Rear Silencer(s) exhaust system:

• reduces exhaust back pressure at the rear

• improves throttle response feel

• supports smoother exhaust flow

• complements the engine's torque and power range

The update offers a clear improvement in sound and driving experience without any adverse side effects.

Direct bolt-on installation

The exhaust system is designed:

• to fit directly into the original mounting points of Mercedes-AMG W205 Sedan models

• for installation without welding or permanent changes

• to preserve the car's original structures and functions

OEM-level fit ensures a clean and unobtrusive finish.

304L Aircraft Grade Stainless Steel

The system is made of high quality 304L grade stainless steel , which provides:

• excellent corrosion and heat resistance

• long service life even in demanding use

• flow-optimized internal structure

• carefully finished TIG welds

The workmanship and materials meet Milltek's premium quality standards.
