Porsche 718 GT4 / Boxster Spyder – Valved Exhaust System
Titanium Rear Section • F1 Race Headers • OEM Valve Integration
Overview
The Porsche 718 GT4 and Boxster Spyder are outstanding driver’s cars, but their factory exhaust note lacks the character and intensity enthusiasts expect. Valvetronic Designs changes that. Drawing from our development of the 992 GT3 RS and GT4 RS platforms, this valved exhaust system injects the high-pitch exotic tone Porsche purists crave—transforming the flat stock sound into something truly spine-tingling.
This system blends lightweight titanium craftsmanship, race-inspired headers, and OEM-level integration to deliver a raw, emotional sound without compromising drivability.
Key Components
Signature Titanium Rear Section
-
Crafted from premium Grade 5 titanium for extreme weight savings and durability.
-
Features a center X-pipe to balance pulses and create a smoother, sharper high-pitched tone.
-
Delivers the exotic character reminiscent of Porsche’s naturally aspirated GT engines.
T304 Stainless Steel Over-Axle Pipes
-
Built with integrated heat shielding to protect surrounding components.
-
Maintains durability under extreme temperatures while improving exhaust flow.
Free Flow F1 Race Headers
-
Equal-length T304 stainless design, tuned for sharper pitch and higher-frequency tones.

Optional standalone controller included for independent valve control.
