Ill either do a how-to or show how on my "custom air horn" thread, I just got the air kit and the pressure gauge is comming. Im about to order the horns and then Ill need some wire, hose, and fittings before I can install them

 

I to an thinking about creating my own kit. Horns I like best so far are from Klein diesel. The air tank in thinking of getting from harbor freight etc. something low profile I may be able to mount under my rear seat. And a compressor from jcwitney and then fittings etc from work. All in $200 is my MAX budget and I'm thinking 152dB from that setup
