Valvetronic Designs 2007-2013 BMW 335i (E9X) Valved Exhaust

Welcome to the latest iteration of the Valvetronic exhaust for the BMW 335i E9X. 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 driver’s side muffler and integrates a 60mm 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 than the stock unit. A very small wiring harness is provided that plugs into BMW’s factory vacuum solenoid in the truck giving the driver the control of the exhaust. Install is incredibly easy and takes roughly 1 hour.

100% REVERSABLE, ALWAYS ABLE TO RETURN TO STOCK AT ANY TIME.

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.

Exhaust tip note:* We are offering our Standard style exhaust tips as a free upgrade. These tips will need to be WELDED on.
