If anyone is interested in upgrading their stock road-runner horn, I went w/a Denali SoundBomb and it now sounds like a locomotive. It's a rupturing 120 decibels, enough to (hopefully) wake up the most text-dazed door-slammer. I got the "split" unit to make install better (on my 1981 CM400). The acoustic unit fit perfectly in the same spot as the factory horn, and I used the factory bracket. It looks like it was born there. I put the compressor on the left side of the bike, on the frame-rail that is just behind the engine cover. They give you 3 feet of high-temp airhose w/the split unit to supply the air from compressor to the horn. I took the gas tank off and hid everything neatly under there. The color and design of the units melts right in, you hardly see it. But you HEAR it. I did get the recommended harness that is sold separately, makes the job much easier and protects your stock electricals. This draws like 20 amps. The blast is shocking!

Back in the day, I installed a pair of FIAMM air horns on my CB175. Similar setup to yours, with a compressor, attached via a relay to protect the electrics.

Lights used to dim when used at night. Most often used to embarrass my mate, in his car in a layby outside his girl friends house. Guaranteed to wake her parents. :lol:
