Product Description:

The Kline Innovation Valved Exhaust for the Ferrari 360 and Challenge Stradale is engineered to replace the restrictive, heavily chambered factory silencer with a high-flow, lightweight masterpiece. By utilizing a trademark X-pipe design, Kline transforms the flat-plane V8’s voice into a piercing, high-pitched scream reminiscent of early 2000s Formula 1 cars.

Performance & Stance

The primary function of the Kline Valvetronic system is to provide a "dual personality" for the 360, allowing for civil road use and uninhibited track performance.

• Acoustic Transformation: The inclusion of a 1D CLR X-pipe raises the exhaust pitch significantly, creating a smooth, high-frequency howl that is much more aggressive than the stock "bubbly" note.

• Extreme Weight Reduction: When crafted from Inconel 625, the rear silencer section weighs approximately 6kg—nearly one-third the mass of the factory unit—significantly reducing weight behind the rear axle for better handling balance.

• Valvetronic Control: In "Valve Open" mode, the silencer is completely bypassed, directing gases through the X-pipe for maximum power and sound. In "Valve Closed" mode, gases are diverted through a harmonically tuned silencer for a drone-free, near-stock cruising experience.

Engineering & Compatibility

Kline approaches the 360 platform with aerospace-grade precision to ensure the system survives the high-vibration environment of the Ferrari V8.

• Material Choices: Available in 304 Stainless Steel for a robust, cost-effective upgrade, or Inconel 625 (Formula 1 grade) for the ultimate in weight savings and heat resistance.

• OEM Integration: The valves are actuated by the car’s original vacuum system, making it a "plug-and-play" installation. It can also be paired with the Kline "Inconel Button" wireless remote for manual override at any RPM.

• Standard Fitment: The system features 63.5mm (2.5-inch) diameter tubing, optimized for the perfect balance between low-end torque and peak horsepower.

Installation Notes

• Tip Options: Owners can choose between double-skinned Stainless/Inconel tips or F1-grade pre-preg carbon fiber tips to match the 360’s rear aesthetic.

• Full Package Gains: While the rear silencer provides the sound, pairing this system with Kline equal-length headers and 100/200 cell sport cats typically results in a power gain of approximately 21 hp across the rev range.

• Challenge Stradale Specifics: For the Challenge Stradale, this system further enhances the car's raw, stripped-back nature by removing even more weight and providing a tone that matches its race-bred pedigree.
