The Kline Innovation Porsche 718 GT4/Spyder/GTS Exhaust System is engineered to transform the driving experience of Porsche’s most track-focused models. Designed for the 2019–2024 Porsche 718 Cayman GT4, 718 Spyder, and 718 GTS, this exhaust replaces the restrictive factory setup with lightweight, high-performance components crafted from F1-grade materials.
At the core of the system is a fully bypassable lightweight Inconel 625 X-pipe silencer, which eliminates the heavy chambered rear silencer, reducing weight dramatically while elevating the exhaust pitch into an exotic, race-inspired tone. Optional removal of the OPF and catalysts, replaced by either HJS motorsport catalysts or de-cat pipes, further unlocks sound and performance, producing an intoxicating high-pitched scream under load.
Kline Innovation’s advanced valvetronic system offers true versatility: stealth mode with valves closed for refined street driving, or raw, unhindered performance with valves open. Optional pre-preg carbon fiber exhaust tips complete the system with a striking visual upgrade that complements Porsche’s aggressive styling.
