I spoke with my contact at Magnaflow about your 2007 BMW 335i. The catalytic converters we offer can be used in all states except California. They told me that you have up to four options for your vehicle.

There are four different converters available that will help reduce the emissions and improve air flow while increasing horsepower and torque.

I recommend part # MF49766 for the front turbo converter, and part # MF49767 for the rear turbo converter. If you wish to replace the driver side underbody you will order part # MF49768, and for the underbody passenger side you will need part # MF49769. My contact said replacing all or some of these components would help with better emission on your BMW.

I have attached some helpful articles about catalytic converters you may want to check out.
