DOES NOT FIT 440 Gran Coupe. True BMW performance, durability, and attractive weight advantages with innovative features places the Active Autowerke BMW F3x 340i exhaust in a class of its own. And now Active Autowerke has developed Gen 2 of this model which has been enhanced to take advantage of the OEM valve system. This system is constructed from 100% Brushed 304-stainless steel and features adjustable brushed, black or carbon Active Autowerke double walled tips, making it ideal both for 2-door and 4-door models. And now the improved sound becomes more pronounced when the valve is opened by the ECU. Rather than creating a complete exhaust system, Active Autowerke opted for a compact design built in a smaller package to deliver more value.
