Description
Kline Audi RS5 V8 Downpipes
The RS5, striking yet elegant. Advancing revs so quickly, the 4.2l FSI v8 engine producing 444hp is a beautiful example of modern engineering. the potential to improve the sound, and power response through exhaust tuning, was enough to make this one of our early marques for a Kline Inconel full exhaust system.
Inconel
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.
Kline Innovation
The first aspect that caught our attention, the manifolds. Crushed and stunted primaries, the absence of any sort of performance collector, and a 400cpsi catalyst located within the power crucial scavenge zone of the manifold. Clearly there was room for significant improvement. It was clear from the beginning why the factory manifolds were built in this fashion, the clearance between heads, block and chassis is just millimetres, designing anything in this space was going to be a challenge. The stock cats were replaced with long primaries, and motorsport grade collectors, drastically improving torque and power response, and giving a more balanced, yet aggressive sound. Rev response is also greatly improved.
