Kline Innovation Valvetronic Exhaust System for McLaren 765LT

Kline Innovation Valvetronic Exhaust System for McLaren 765LT

The McLaren 765LT is the more aggressive, track-oriented counterpart to the 720s. With its powerful M840T engine generating 755hp and 800nm of torque, it pushes the boundaries of performance. The car’s improved aerodynamics and 80kg weight reduction complement each other, resulting in higher apex speeds and enhanced handling. However, the exhaust, despite being made from titanium, falls short in terms of weight reduction and durability, and its sound doesn’t reach its full potential.

The Sound

• Replacing the thick sidewall titanium with ultra-lightweight Inconel 625, not only reduces weight but also amplifies the high-pitched resonance of the exhaust. The addition of Kline’s trademark 1D CLR tight radius x pipes further raises the pitch, creating an exotic, high-pitched race car-like tonality. When the valve is open, the exhaust gases flow freely, unrestricted, maximizing both performance and sound. On the other hand, when the valve is closed, the exhaust gases are directed through a specially designed micro-silencer, enabling the car to be driven quietly, with a nearly stock sound during cruising. However, once the valve is open, it unleashes a rich, raucous, high-pitched exotic scream.

Performance

• The McLaren turbo engines offer significant tuning potential. By removing the stock 600 cpsi catalytic converters and replacing them with either 100 cpsi or 200 cpsi motorsport catalysts or racing test pipes, along with necessary adjustments to the air-fuel ratios, power gains of up to 40hp can be achieved. For even greater gains, a full ECU remap in conjunction with a full Kline exhaust system can yield up to 80hp of additional power.

Stainless Steel

• At Kline, they adhere to industry standards by utilizing 304-grade stainless steel for our exhaust systems. This grade offers a well-balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production, ensuring the construction of practical and durable exhaust systems. It’s important to note that while stainless steel has a density similar to regular steel, it is relatively heavier and possesses slightly lower tensile strength. Nevertheless, it meets the requirements for creating high-performance exhaust components capable of producing 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 favored in Formula One exhaust systems and has been selected 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.
