Porsche 718 Cayman GT4 4.0L Valved Axleback Exhaust System (2019–2023)

Upgrade Your Porsche 718 Cayman GT4 4.0L with a Valved Axleback Exhaust for a Sharper Sound

Designed for the Porsche 718 Cayman GT4 with the 4.0L naturally aspirated flat-six engine, this valved axleback exhaust system upgrades the rear section of the factory exhaust with a freer-flowing performance design for a more aggressive and engaging exhaust character.

Manufactured from high-quality stainless steel with a brushed finish and 1.5mm wall thickness, the system features a pneumatic valved design that allows you to switch between a more refined exhaust note and a louder, more performance-focused sound. It is an ideal upgrade for GT4 owners who want improved rear-end sound character while maintaining a clean vehicle-specific fitment.

The system is available with your choice of Glossy Black Stainless Steel Tips, Carbon Fiber Glossy Black Tips or Chrome Tips. Professional installation is recommended to ensure correct fitment, exhaust alignment and proper valve operation.
