The 981 Cayman and Boxster are perfectly balanced, razor-sharp and endlessly rewarding — but from the factory the sound never matches the experience. The Valvetronic Designs cat-back system fixes that. Measuring 2.5 inches from the headers back, it transforms the 981's tone into a motorsport-inspired symphony.

With valves open, gases flow straight through to a large X-pipe and exit via 3.5-inch tips for the raw, high-pitched sound this chassis deserves. Close the valves and the system calms down to a refined, neighbor-friendly tone.

Sound dynamics

• Valves open: free-flowing, raw, high-pitched motorsport character.
• Valves closed: quieter and refined for comfortable daily use.
• Vacuum-actuated valves operated via the supplied controller or integrated with OEM operation.

Features

• Fully mandrel-bent tubing for maximum flow.
• Precision TIG welds for strength and reliability.
• Built from Grade 5 titanium for lightweight performance.
• 3.5-inch tips designed to complement the 981's rear styling.
• Vacuum-actuated valves for total sound control.
• 15 lbs lighter than the factory exhaust.
