KLINE INNOVATION
Valvetronic Exhaust System — McLaren 720S
The McLaren 720S, with its 4.0L twin-turbo V8 producing 720 horsepower and a blistering 0–60 time of 2.7 seconds, was designed to shake up the established supercar industry. Despite ferocious acceleration and superb handling, the current trend for turbo-induction supercars has the 720S in need of a sonic makeover. Kline’s primary design criteria: make the 720S scream like a supercar should.
🔊 THE SOUND
High-flow catalysts or racing pipes open the volume up significantly, while Kline’s signature 1D CLR tight-radius X-pipe raises the pitch to where a supercar should be. Crafted from premium F1-grade Inconel 625 superalloy, the system not only vastly reduces weight but adds a special tonal quality that can only be achieved with the Kline Inconel range. Available in racing configuration for optimum sound and performance, or a choice of 100 or 200 cell high-flow sports cats. The modular catalysts section allows for rapid swapping with racing pipes depending on intended use.

🏗️ MATERIALS
Inconel 625 Superalloy
The ultimate choice for durability and heat resistance. Widely used in aerospace and Formula One exhaust systems, Inconel 625 achieves an outstanding strength-to-weight ratio comparable to titanium. This enables thin sidewall materials while maintaining structural integrity — producing lightweight components with remarkable fatigue resistance. Full Valvetronic System: 5.5 kg
304-Grade Stainless Steel
Industry-standard 304-grade stainless steel offers a well-balanced combination of moderate strength, thermochemical stability, cost-effectiveness, and ease of production. A practical and durable choice for high-performance exhaust components. Full Valvetronic System: 11 kg
