Description
Disclaimer : Lead time just for a pair of side pipes is 5 - 6 weeks.
The Kline Innovation Inconel Side Pipe Exhaust System is engineered to enhance the sound, performance, and weight savings of the Porsche 718 GT4 RS and Porsche 718 Spyder RS. Designed for Porsche's high-performance 500-horsepower flat-six platform, this lightweight exhaust system combines F1-grade Inconel 625 construction, Valvetronic technology, and an optimized exhaust design to deliver an exotic motorsport-inspired sound and improved exhaust flow.
By replacing the heavy factory chambered rear silencer with a lightweight Inconel 625 X-pipe and fully bypassable Inconel silencers, the Kline Innovation system significantly reduces exhaust weight while producing a higher-pitched, more exotic exhaust note. The optional exhaust configurations allow further sound enhancement through the removal of the original gasoline particulate filter (OPF) and catalytic converters, with options for HJS motorsport catalytic converters or decat pipes.
SOUND AND VALVETRONIC TECHNOLOGY
The Kline Innovation rear Valvetronic system provides adjustable exhaust sound, allowing the driver to select a quieter, more restrained sound with the valves closed or an aggressive, unrestricted exhaust note with the valves open. The lightweight Inconel silencers are designed to deliver an exotic, high-pitched sound that complements the Porsche flat-six engine.
Replacing the original OPF with a specially designed silencer helps eliminate a major exhaust restriction while minimizing the exhaust drone commonly associated with OPF removal. For additional sound enhancement, the system can be configured with either 100-cell HJS motorsport catalytic converters or decat pipes. The optional F1-grade prepreg carbon fiber exhaust tips provide a premium motorsport-inspired finishing touch.
PERFORMANCE AND WEIGHT REDUCTION
The Kline Innovation Inconel Side Pipe Exhaust System is designed to improve exhaust flow, reduce weight, and enhance engine sound. Replacing the factory catalytic converters with 100-cell HJS motorsport catalytic converters or decat pipes, along with correcting the resulting air/fuel (A/F) ratios, can deliver power gains of up to 20 horsepower, depending on the configuration and engine calibration.
The system uses carefully selected pipe diameters and cross sections to maintain an optimal balance between torque and power. Its lightweight construction helps reduce vehicle weight, making it suitable for drivers seeking enhanced performance and a more focused motorsport driving experience.
