Fabspeed Porsche 992 Twin Turbo / Twin Turbo S Cat-Back Valvetronic Maxflo Exhaust System (2021+)


With PSE on and valves open, the Cat-Back Valvetronic Maxflo Exhaust turns your 992’s exhaust note into a true neck-breaker with a significant increase in volume. Get a deep tone and aggressive pops on downshift as well as turbo spooling sounds. With PSE off and the valves closed the exhaust note is tame and totally drone-free. In-cabin conversations are just as easy as they were with the stock exhaust.


With our signature cast X-pipe and all cnc mandrel-bent tubing, this system significantly outflows the factory system. When testing on our AWD Dynojet power was up across the board. Down low, the Turbo spools faster, netting 19.6 WHP and 32.7 ft/lbs of TQ at 3100 RPM. Max power gains are at 4800 RPM where it gained 48.7 WHP and 53.7 ft/lbs of TQ. That’s a gain of 55 HP at the crank! See our dyno graph above for more details.
