Kline Audi RS7 DECAT Cat Pipes

The RS7 has a 4.0 TFSI twin scroll twin turbo V8 engine, producing 605hp is a beautiful example of modern engineering. As with all turbo induction engines, the potential to improve the sound, and power response through exhaust tuning is substantial!

Replacement of the stock 600cpsi catalysts, with either high flow HJS cores, or de-cat pipes, opens up the sound significantly, as well as drastically improving turbo spool for increased power, and reduced spool time. This coupled with the twin 70mm dual oversized pipe, allows the engine to reach its full potential.


HJS HDPE motorsport 100 cell, or 200 cell catalysts available, or de-cat pipes for optimum performance and sound


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.
