KLINE VALVETRONIC EXHAUST SYSTEM FOR AUDI RSQ8 & SQ8
The Audi RSQ8 stands as a potent and capable utility vehicle. However, its sound was deemed somewhat reserved, failing to fully embody the true character and strength of this formidable machine.
THE SOUND
By replacing the factory catalysts, which tend to be restrictive, with either 100 or 200 cell HJS HDPE motorsport catalysts, the exhaust sound is significantly enhanced. Additionally, the incorporation of a 20-degree x pipe helps blend the gases out of phase, resulting in a raised pitch for the exhaust note and the reduction of undesirable drone.
In the rear section, the exhaust system utilizes the car’s stock electronic valve control system. When the valve is closed, the exhaust gases are redirected through a series of chambers and acoustic fill sections, resulting in a smooth and quiet ride during cruising. However, when the valve is open, the silencer is completely bypassed, allowing for an unobstructed and commanding roar that befits the powerful nature of this vehicle.
PERFORMANCE
Through the performance-oriented removal of restrictions from the silencer section and the installation of a completely unrestricted free-flow system when the valve is open, the exhaust achieves optimal efficiency, resulting in noticeable power and torque improvements.
The introduction of racing pipes brings significant gains, with an impressive increase of 37 horsepower and 48 Nm of torque.
STAINLESS STEEL
In the realm of exhaust manufacturing, the prevailing industry standard revolves around the utilization of 304-grade stainless steel. This particular grade of stainless steel offers a well-balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production. It enables the construction of exhaust systems that strike a reasonable balance between affordability and functionality, ensuring long-lasting durability. However, it is worth noting that stainless steel is relatively heavier when compared to alternative materials. While it shares a similar density with regular steel, it possesses slightly lower tensile strength. This limitation hinders the potential for creating high-performance exhaust components using stainless steel. Additionally, in terms of sound characteristics, the thicker sidewalls required by stainless steel may result in a somewhat less vibrant and dynamic exhaust note compared to the aforementioned materials.
INCONEL
When it comes to ensuring durability and heat resistance in the aerospace industry, the utilization of Inconel 625 is of utmost importance. This extraordinary material finds extensive applications in the manufacturing of critical components, particularly exhaust turbine blades for high-performance jet engines. Notably, Inconel is the preferred choice for Formula One exhaust systems and has been selected by manufacturers involved in prestigious hypercar projects like the McLaren P1 and Aston Martin 177. These applications greatly benefit from Inconel’s exceptional ability to withstand extreme temperatures exceeding 1000°C while prioritizing lightweight design.
Inconel exhibits extraordinary properties, including remarkably high tensile strength and outstanding thermochemical stability. Its tensile strength is comparable to that of titanium, resulting in an exceptional strength-to-weight ratio. Consequently, Inconel allows for the use of thin sidewall materials while preserving structural integrity, enabling the production of lightweight components that demonstrate resistance to fatigue over prolonged periods. However, working with Inconel presents certain challenges due to its difficult machinability and specific welding requirements, demanding specialized skills and time-consuming techniques. Additionally, the unique properties and specialized manufacturing processes associated with Inconel contribute to its higher cost as a raw material.
CATALYST
To achieve the optimal balance between torque and increased power, all cross sections have been enlarged by approximately 10% compared to the stock dimensions.
