Overview

Upgrade the Mercedes-Benz C-Class C63 & C63 S Saloon 4.0 Bi-Turbo V8 (2015+) with a Milltek Sport cat-back exhaust. Milltek builds each system around the car it fits: mandrel-bent T304L stainless pipework, a larger bore than stock for freer flow, and a tuned sound you choose, from quiet and refined to loud and uncorked.

Sound options

Valved systems let the car switch between quiet and loud.

Choose your setup

Sound: the system type and sound level.
Optional Valve Remote: add a Milltek valve remote so you can open and close the exhaust valves yourself.
