Description
These catted stainless steel downpipes with integrated heat shielding are engineered specifically for the 4.0L twin-turbo V8 found in the Mercedes-AMG C63S. Designed to improve exhaust flow and enhance overall performance, they also significantly reduce underbody temperatures through premium thermal management.
Constructed from high-grade T304 stainless steel and TIG-welded for strength, the WERKE catted downpipes provide smoother exhaust velocity, improved turbo response and a refined, more purposeful exhaust tone. The integrated heat shielding helps protect surrounding components, making this an ideal upgrade for both tuned street vehicles and hard-driven track applications.
Featuring precise OEM-style fitment, this system installs cleanly using factory mounting points and is compatible with factory or aftermarket exhaust systems.
