The long awaited Valvetronic Designs E9X M3 system is finally here. These systems are fully mandrel bent for maximum flow and are contructed out of T304 stainless steel, the highest quality material on the market. Our dream is to offer the BMW community an incredible valved exhuast without charging the dreaded "M tax" and that dream has come true. For far too long these systems have been out of reach for most people, but no longer. This system comes with everything you need to have your E9x M3 sound like a beast on your favorite backroad, or cruise to the shops without alerting the authorities. Your time to take control of your E9X M3 sound is now.
