Description
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 development of the 992 GT3 RS and GT4 RS platforms, this valved exhaust system delivers a high-pitch exotic tone while blending lightweight titanium craftsmanship, race-inspired headers, and OEM-level integration.
Key Components
- Signature Titanium Rear Section: Grade 5 titanium construction with a center X-pipe for balanced pulses and a sharper high-pitched tone.
- T304 Stainless Steel Over-Axle Pipes: Integrated heat shielding, durability and improved exhaust flow.
- Free Flow F1 Race Headers: Equal-length T304 stainless design tuned for sharper pitch and higher-frequency tones.
- OEM Valve Integration: Compatible with Porsche PSE button via factory vacuum lines. Valves open for maximum flow and aggressive sound; valves closed route through quad-chamber mufflers for reduced volume.
- Optional Standalone Controller: Provides independent valve control.
Why Upgrade?
- Aggressive, high-pitched sound inspired by Porsche GT engines.
- Daily-driveable operation when valves are closed.
- Performance-oriented flow and throttle response.
Technical Highlights
- 34.8 lbs lighter than stock.
- Precision TIG welding.
- 100% bolt-on and reversible design.
- OEM valve control retained.
