Deep, Aggressive Exhaust Note:
This system brings out the best of Porsche’s twin-turbo flat-six — deep, throaty, and exotic, with crisp turbo whistle and refined aggression. No drone, just pure driving emotion. Open the valves and let the car speak.
Improved Exhaust Flow = More Power:
Crafted for performance, the free-flowing design significantly reduces backpressure over stock. Gain horsepower, torque, and faster turbo response throughout the rev range.

Built from premium T304 stainless steel, TIG welded with precision, and designed to endure the abuse of daily driving, track sessions, and spirited canyon runs — while looking as good as it sounds.
Lightweight & Performance-Oriented:
Drop unnecessary weight versus the OEM system, contributing to better handling and overall performance. Form meets function, without compromise.
OEM+ Fitment, No Hassle:
Designed for a direct bolt-on installation, the Untd. Valved Cat-Back works seamlessly with stock and most aftermarket downpipes. Uses factory hanger points for a clean, factory-style install.
Wireless Valve Controller Included:
Comes complete with a plug-and-play remote valve control system, allowing instant operation of the valves without needing to touch drive modes or menus.
The factory exhaust hides the true voice of the 991.2’s twin-turbo flat-six. This cat-back system unlocks the character and emotion that Porsche engineered into the 3.0T — and lets you decide when to keep it quiet or let it sing.
