992 TURBO 400C CATTED DPS

The 992 platform is widely considered the modern performance car benchmark. But like all turbocharged Porsches, it comes with one big compromise—muted sound. At Valvetronic Designs, we restore the drama with our Sport and Race configurations, transforming your 992 into the emotional driving machine it was always meant to be. Sound Dynamics: Valves Open: Exhaust gases flow unrestricted through a large X-pipe, delivering the raw, motorsport tone you’ve been craving. Expect aggressive overrun crackles and a naturally aspirated character, reminiscent of Porsche’s legendary 917 race cars ripping down the straights. Valves Closed: Sound is routed through our quad-chamber muffler, significantly reducing volume for refined cruising and early-morning starts, all while maintaining tone quality. The result: a system that brings the magic back to the 992 platform—balancing daily comfort with track-inspired exhilaration. Features: Constructed from Brushed T304 Stainless Steel or Ti 6Al-4V (Grade 5 Titanium), Factory valve integration – rapid open/close response with OEM controls, Mandrel-bent piping for maximum flow and minimal restriction, Precision TIG welds for strength and durability.
