anybody thought of a custom car horn?
 

just browsing and came across this.

sounds like a waste. I have a street bike and being heard/seen in very important. I would assume in the FRS/BRZ being such a small car - your horn should be a horn and mistaking for anything else. I actually installed a air-horn which was very loud.

This seem like it would have done really well in the 90s.

These are loud and small. The relay sucks, buy a quality one and use that instead. And some good wiring, draws a lot of current.

"Dual-tone air horn from Stebel of Italy available in Black or Chrome. Loud enough to convince other drivers that there's a derailed freight train barreling down on them. Don't press the horn button in the garage, it hurts! At 139dB it can be heard for almost 3 city blocks! YEEEOOOWWW!"

They ain't kidding. These things will rock your world if you accidentally honk it in an enclosed space. Trust me on that one....
