Get the best of both worlds with our Valvetronic Exhaust System for all 2009-2011 911 Carreras. Treat yourself to a smooth and civilized exhaust note around town and then open up the valves for an aggressive race-bred sound on the open road. This system works with either the PSE (Porsche Sport Exhaust) button on factory PSE-equipped cars, or order it with our valve controller kit to get complete control over the valves on a Non-PSE Carrera.
SOUND:
With the valves closed the exhaust note has a classic smooth flat-six sound that is slightly louder than stock. It’s totally drone-free and in-cabin conversations are as easy as they were when stock. Open up the valves to treat yourself to a raw race-bred sound similar to what you’d hear on a Porsche Cup car. In this mode the X-Pipe and Mufflers are bypassed which creates a very aggressive sound that is much louder than stock.
