This is the Valvetronic Designs cat-back system for the 991.1 platform, engineered from the ground up to deliver a genuinely rich, F1-inspired sound while staying comfortable and refined with the valves closed. A large center X-pipe smooths exhaust flow and balances aggression with sophistication for the ideal 991 soundtrack.

Sound dynamics

• Valves open — gases flow with minimal restriction for a sharp, high-pitched F1-style sound
• Valves closed — tone is tamed significantly, cutting cabin frequencies for calm, refined daily driving

Features

• Available in Anodized Gold T304 stainless steel or Blue Burnt titanium
• Vacuum-actuated exhaust valves with controller for OEM-like operation
• Standalone valve control option for vehicles without factory valves
• 21.8 lbs lighter than the factory exhaust (T304 stainless version)
• Fully mandrel-bent piping for maximum exhaust flow
• Precision TIG welds for strength and durability
• 100% reversible — always able to return to stock
