Fabspeed Valvetronic Cat-Back Maxflo Exhaust with Helical Valves for 2019+ Porsche 911 Turbo (992) [3.7TT H6]
Treat your 992 Turbo to the finest cat-back exhaust solution on the market. This valveed exhaust system is plug-and-play with the factory PSE system so you can turn PSE off for quiet highway cruising and turn PSE on for ripping Twin Turbo sports car sound!
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.
