Valvetronic Cat-Back Exhaust

The Kline Innovation Valvetronic Cat Back Exhaust system is engineered as a direct replacement for the factory exhaust on the 2022+ Porsche 718 GT4 RS and 2022+ Porsche Spyder RS. This system aims to enhance the vehicle's auditory experience, reduce weight, and improve performance. Constructed from premium materials, customers can choose between F1-grade Inconel 625 or 304 stainless steel. Inconel 625, known for its extreme tensile strength and heat resistance, is significantly lighter than stainless steel (7.9kg vs 13.5kg for the rear silencer). This construction choice contributes to the overall lightness of the system, a key aspect for performance-oriented vehicles like the GT4 RS. The system incorporates Kline's Valvetronic technology, allowing drivers to switch between a stealth mode with closed valves and an open, aggressive exhaust note. The design also includes options for replacing the stock OPF (Otto Particulate Filter) with either de-cat pipes or HJS motorsport catalysts (available in 100-cell or 200-cell configurations). This modification is crucial for unlocking performance gains of up to 20 hp by removing the most restrictive component in the exhaust path, while the specially designed silencer is intended to mitigate exhaust drone. This exhaust system is designed to fit 2022+ Porsche 718 GT4 RS and 2022+ Porsche Spyder RS models. There are specific options for including OPF Link Pipes with heat shielding, and for the catalytic converters, buyers can choose between no catalysts (decatted), 100-cell, or 200-cell HJS motorsport catalysts.
