Audi Exhaust valve delete plugs (3 wire)
 

Another part I have leftover from my B9 S5 is a set of 3-wire exhaust valve control plugs. I used these plugs to keep the exhaust valves open all of the time. I used them for about a month before I decided that I wanted to be able to use the exhaust both open and closed. I understand that these will work on other Audi 3-wire exhaust valves as well.I have the plugs for the valves and valve controller connection. This eliminates the fault when you simply unplug the exhaust valves. Price = $30 for all 4 pieces.
