I bought a C63S 3 months or so ago and had it in for a service recently. The MB tech pointed out the lack of cats and very decent looking downpipes had been fitted instead.
Would the car have to be remapped to get rid of any fault codes or can the downpipes be fitted as a stand alone modification with no ECU tweaks?
