Product Overview
The Acoustiq Atelier Valvetronic Exhaust System for the Porsche 718 GT4, GTS 4.0, and Spyder is a precision-engineered performance upgrade designed for drivers who demand refined sound, improved performance, and motorsport-grade craftsmanship.
Featuring CFD-optimized flow paths, AI-assisted acoustic modeling, and a modular system architecture, the Acoustiq system produces a resonant, exotic exhaust note with reduced drone while improving exhaust flow and reducing weight.
This rear section can also be integrated with optional headers and over-axle sections (sold separately) to support different performance setups and sound profiles.
Constructed from aerospace-grade stainless steel or titanium, each exhaust system is handcrafted and individually serialized. The integrated Valvetronic system allows drivers to control the exhaust tone on demand—delivering an aggressive sound when open while maintaining refined driving comfort when closed.
The system integrates seamlessly with the factory Porsche Sport Exhaust (PSE) system. An optional wireless remote kit can provide full manual valve control beyond factory settings.
