Exhaust system Capristo Mercedes-AMG GT R C190

02MB08903017

Exhaust system for the Mercedes-AMG GT R C190 with the M178 4.0 biturbo V8. The GT R is the hardest road version of the C190, and the factory system is still built to the same noise limits as the softer cars in the range.

How it works

The valves stay closed at light load, so cruising noise is close to standard. Opened, the gas path shortens and bypasses the damping chambers, which is where the volume and the sharper response come from. The flat-crank M178 has a firing order unlike the rest of the AMG V8 family, and this is the part that lets it through.

Material and build

T309 (1.4828) stainless steel, rated for continuous temperatures above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany, developed on 3D laser scans of the original pipework.
