Kline Innovation Valvetronic Exhaust System for 991.2 Porsche 911 GT2 RS

Kline Innovation Valvetronic Exhaust System for 991.2 Porsche 911 GT2 RS

The much-anticipated 991 GT2 RS, boasting 690hp, 750nm of torque, and a blistering 0-60mph sprint time of 2.7 seconds, has been declared the most powerful incarnation of the legendary GT2, making it the mightiest 911 ever to roll off the production line. Although the factory-fitted titanium exhaust presents a sound improvement over its predecessor, the 997, it still falls short of fully encapsulating the raw spirit of this supercar. However, the specialists at Kline are renowned for transforming subdued turbo noises into the vibrant roar of a supercar.

The Sound

• Leveraging the successful design innovations of the 996 and 997 range, the benchmark for the 991 GT2RS exhaust design was set significantly high. Kline’s trademark x pipe geometry, harmonically tuned silencers, Inconel 625, and proprietary acoustic silencer packing materials all come together to create a system that has garnered fame for its impeccable sound. This includes zero drone and a high-pitched, fiery howl at higher rpms and full throttle. By integrating the standard valvetronic vacuum system, Kline managed to include their proprietary valvetronic silencers, ensuring a quieter ride when the valve is closed and a more aggressive sound when the valve is open.

Performance

• Options are available with racing pipes for peak performance and sound, or with 100 or 200 cell HJS HDPE catalysts. The most substantial gain with racing pipes is 42hp and 59nm, while 100 cell and 200 cell catalysts offer gains of 22hp and 18hp, respectively.

Stainless Steel

• In the realm of exhaust manufacturing, 304-grade stainless steel is often selected due to its adequate strength, thermochemical stability, cost-effectiveness, and ease of production. However, stainless steel, while suitable for constructing robust exhaust systems, is heavier than alternative materials. It has a density similar to standard steel, but its tensile strength is somewhat lower, restricting its utility for high-performance exhaust components. Additionally, the necessity for thicker walls in stainless steel could lead to a more muffled and less lively exhaust sound.

Inconel

• In the aerospace industry, Inconel 625 is highly regarded for its resilience and heat resistance. It is widely used in creating critical components, especially exhaust turbine blades for high-performance jet engines. Inconel is favored in Formula One exhaust systems and has been chosen by manufacturers for distinguished hypercar projects such as the McLaren P1 and Aston Martin 177. Capable of withstanding temperatures beyond 1000°C, Inconel focuses on a lightweight design. However, the complexities of working with Inconel due to its challenging machinability and specific welding requirements demand specialized skills and intricate techniques.

Carbon Fiber

• Carbon fiber reinforced polymer, possessing a tensile strength-to-weight ratio that outshines all metals, exhibits exceptional properties. Its lightweight nature and superior strength make it a sought-after material in various industries, including automotive and aerospace. Carbon fiber components contribute to weight reduction and offer improved rigidity, enhancing overall vehicle dynamics.
