Kline Innovation Valvetronic Catback Exhaust System for AM5 Aston Martin DB11

Kline Innovation Valvetronic Catback Exhaust System for AM5 Aston Martin DB11

The Aston Martin DB11 stands as an impressive Grand Tourer, showcasing its prowess on the road. Equipped with a potent 4.0 twin-turbo V8 engine, it possesses the sonic potential to surpass expectations, and that’s exactly what has been achieved.

The Sound

• The rear silencer section, in collaboration with the car’s stock electronic actuated valve system, delivers unrestricted flow when the valve is open, bypassing the silencer for optimal performance and an aggressive sound. On the other hand, when the valve is closed, the exhaust gases are directed through a series of chambers and acoustic-filled sections, meticulously tuned to enhance low RPM torque and maintain a quiet volume during cruising.

Stainless Steel

• At Kline, industry standards are diligently followed, utilizing 304-grade stainless steel in their exhaust systems. This grade ensures a well-balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production, resulting in the construction of practical and durable exhaust systems. It is worth noting that while stainless steel shares a similar density with regular steel, it is slightly heavier and possesses slightly lower tensile strength. Nonetheless, it fulfills the requirements for creating high-performance exhaust components that produce captivating exhaust notes.

Inconel

• For exceptional durability and heat resistance, Kline turns to the ultimate choice: Inconel 625, widely employed in the aerospace industry. This exceptional material finds extensive application in the manufacturing of critical components, including exhaust turbine blades for high-performance jet engines. Inconel is highly regarded in Formula One exhaust systems and has been favored by manufacturers involved in prestigious hypercar projects such as the McLaren P1 and Aston Martin 177. The advantages of Inconel lie in its exceptional tensile strength and thermochemical stability. Comparable to titanium in terms of tensile strength, Inconel achieves an outstanding strength-to-weight ratio, enabling the utilization of thin sidewall materials while maintaining structural integrity. This facilitates the production of lightweight components that exhibit remarkable resistance to fatigue over extended periods. However, working with Inconel presents challenges due to its difficult machinability and specific welding requirements, demanding specialized skills and time-consuming techniques. Moreover, the unique properties and specialized manufacturing processes associated with Inconel contribute to its higher cost as a raw material.
