Fabspeed Porsche 992 Carrera Cat-Back Valved Maxflo Exhaust System (2019+)

Drawing on 25+ years of air- and water-cooled Porsche experience, Fabspeed’s Valved Maxflo Cat-Back restores the classic flat-six voice the 992 Carrera lost from the factory. PSE on, the exhaust opens up with a deep tone, turbo spool, and aggressive downshift pops; PSE off, it’s tame and completely drone-free — cabin conversations stay as easy as stock.

Valve quality

The system uses Helical Limited (UK) exhaust valves — the same supplier Porsche, Ferrari, Lamborghini, McLaren, and Aston Martin use — imported exclusively for North and South America by Fabspeed. Cheap aftermarket valves are the number-one failure point on rear-engine cars; these are engineered not to fail.
