Add the ability to go from loud to factory at the click of a button with the Valvetronic Designs E9x 335 exhaust!
Welcome to the latest iteration of our Valvetronic exhaust for the BMW E9x 335i. You no longer have to compromise between the exhaust sound you want and the drone you don’t. The factory BMW exhaust is very tame, and what this system does is allow you to keep the tame nature of the system when the exhaust valve is closed and have that glorious straight 6 sounds when the valve is open. This system is constructed of T304 stainless steel and is fully mandrel bent for maximum flow. This system replaces your factory drivers side muffler and integrates a 60 mm exhaust valve that is controlled by a key fob style controller that can be placed on your key chain or anywhere in the car you desire. The system mounts directly to the factory BMW exhaust hangers and is roughly 11 pounds lighter that the stock unit. A very small wiring harness is provided that plugs into BMW’s factory vacuum solenoid in the trunk giving the driver the control of the exhaust. Install is incredibly easy and takes roughly 1 hour.
Each system is handmade right here in Central Pennsylvania by true craftsmen and is the product of over a year and a half of development. The system is designed to fit both E90 and E92/93 models.
* ONLY fits with factory exhaust systems. This system does not fit any other system aftermarket system.
