Kline Valvetronic Rear System for Audi R8 V10 2019+
The Audi R8, with its v10 engine, aluminium monocoque spaceframe, and striking yet refined styling is a formidable supercar, yet still refined enough to be used as a daily driver. with this in mind the sound and performance criteria for the exhaust was clear, to sculpt an exhaust that would be comfortable at cruising speeds, yet raw and powerful in sound and nature in high revs.
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.
Performance
Removal of the secondary catalysts from the silencer section, and addition of a completely free flow system under valve open, result in optimum efficiency from the exhaust, and some moderate power and torque gains
21hp and 27 nm power and torque gain
The Sound
Incorporating all the regular innovations from kline, perfect x pipe geometry for that incendiary howl we have become renowned for, as well as a valvetronic system that allows you to drive your R8 silently when cruising, yet the most intoxicating high pitched aggressive vocal when the valves open.
Under valve closure the exhaust gasses are diverted through a series of chambers and acoustic sections to completely remove any cabin noise and drone, at valve open the exhaust becomes completely free flow for optimum performance and sound, the gases only passing through our trademark x pipe, to effectively raise the pitch of the exhaust note.
The valves are actuated by the cars factory vacuum system, and can be controlled by our new wireless remote INCONEL BUTTON kit
Cross Sections
All cross sections have been increased from stock by around 10% to give the best balance of torque, and increased power
Silencer section, 65mm 1D CLR X-pipe.
