Porsche 981 Cayman / Boxster – Valved Sport Exhaust System
Titanium Construction • Valved Control • Signature F1 Tone
Overview
The 981 Cayman and Boxster platform is a dream—perfectly balanced, razor-sharp in handling, and endlessly rewarding. But from the factory, the sound falls short of the experience. That’s where Valvetronic Designs steps in.
Our cat-back exhaust system transforms the 981’s exhaust note into a motorsport-inspired symphony. Measuring 2.5 inches from the headers back, this setup drastically elevates tone, character, and raw emotion. With the valves open, exhaust gases flow straight through to our large X-pipe and exit via 3.5-inch tips, delivering the raw, high-pitched sound the 981 chassis deserves. Close the valves, and the system calms down, offering a refined and neighbor-friendly tone.
With precision engineering, lightweight titanium construction, and our proven valve control technology, this system unlocks the true voice of the 981.

ECU tuning works by modifying the software that controls engine parameters like fuel mixture, ignition timing, and boost pressure to optimize performance.
The process of installing a tune depends on the vehicle’s make and model. Some tunes are installed by connecting a tuning device to your car’s OBD-II port and uploading the tuned software, others may require ECU unlock.
