Gen 2 of Active Autowerke's rear exhaust for the 340i and 440i works with the factory valve system. When the ECU opens the valve, the sound becomes noticeably fuller. Rather than a complete system, it's a compact rear section, which keeps the cost down.

What you get

  • Valved rear exhaust that uses the OEM valve system.
  • Brushed 304 stainless steel construction.
  • Adjustable double-walled tips that suit both 2-door and 4-door cars.
  • Four tip finishes: brushed, black, carbon, or carbon over black.

Good to know

  • Does not fit the 440i Gran Coupe.
