Can you pull the horn off and switch it with the outlet adapter? I notice that most people pull both of the horns off because one of the valves points the wrong direction (because they're not at 180deg from each other). Doing this might allow you to use both horns and spify up the appearance a bit. You could do this with my GFB hybrid, just wondering if these would work as well. I guess the adjustment between full BOV and full BPV would be backwards?

TIA
