Kline Mercedes S500 Coupe W222

This is the exhaust system for the Mercedes S500, sixth generation of the S-Class with the V8 Bi-Turbo boasting an impressive 455 PS. Here at Kline, we felt that the exhaust note should fulfil its bull baritone potential.

The Sound

Replacing the restrictive stock cats with our 100 CPSI race cats, or decats, allows us to open the sound and performance significantly.


Available in super lightweight F1 grade inconel 625, or 304 stainless steel.


Inconel 625, as used in the aerospace industry where extremely durable and heat withstanding components are required, for example for the exhaust turbine blades in high performance jet engines. Inconel is also used for the manufacture of Formula1 exhausts and has also been used by some manufacturers on hypercar projects such as McLaren P1, Aston Martin 177, where lightness is a factor, and exhaust temperatures regularly exceed 1000°C.
The basic properties of Inconel are characterised by extremely high tensile strength, and extreme thermo chemical stability. Because of the high tensile strength of Inconel (roughly the same strength to weight ratio as titanium), very thin sidewall material can be used while still maintaining structural integrity, resulting in very lightweight components that will not fatigue over time. Using Inconel requires a high skill level and is a very time-consuming process which is all worthwhile for the highest quality exhaust system.
