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.
