The FVD Brombacherexport version muffler with valves offers the very best sound and performance without compromise. This muffler is also based upon the past success of our sound version mufflers for the Boxster 's and Cayman 's. It is a German export version intended for cars outside of Germany that enjoy less strict decibel requirements. Our entire Brombacher line of exhausts is manufactured to our specifications by m exhaust, gmbh in Germany. This muffler has been designed using principles from the m turbo line of mufflers and is uniquely made with double perforated sound absorption tubes based on the halbgegenstromprinzip (half counter current principle). The acoustic silencer absorption tubes are made in a trapezoidal pattern and are perforated with varying diameters, which isolate and dampen the unwanted frequencies that create drone. These perforated tubes present much less flow restriction than traditional baffle plates at higher gas velocities, and consequently translates into larger horsepower and torque gains throughout the entire rev range. Please note: this muffler is for pdk models only. Please enquire with us if you have a manual transmission.
