Here is my input to the regional section on trainhornforums…
My setup is a Siege Kong MK1 horn, 200 psi air system with a Viair 380C compressor and a 3 gallon tank. The horn is supplied by a 3/8" airline and a G4 valve.
Its all fitted to and old Bimmer Coupe. Pictures are comming up within a few days…
My friend fitted a Siege Anvil horn system to his car. That was the horn I was complaining about in the maintenance section.
