Being 8 years later since that car came out, Im sure BMW has become ever more stringent in keeping emissions low. With stock mid-pipes left in place, Im sure this car would pass any tailpipe sniffer with ease. Here in NY we get a plug-in OBD scan for any car over 2 years old, anything under 2 years old gets a $10 safety sticker and you're on your way. "
