Authoritative Horns for the Road?

What are some ideas and preferences for good road horns, air and electric? I've used Wolo "Airsplitter" in the past, and it seemed to develop a lag, from time to time. How about:
PIAA 85110 115db 400HZ + 500HZ Sports Horn

 

I have been using an old set of Hadley bully air horns for a while now. I could not find a good place for my Nathan's. I was trying to get the Hadley ambassadors to fit but they hung down below the frame too far.

I find I get zero lag if I use the button to fire a solenoid on an already charged air system. If you have to wait for anything to spin up it has already been too long.

 

general lee horns would be sweet.

 

In my 96 I have the factory horn plus four horns out of one Cadillac ran via relay. The Cadillac horns are all different tones.

 

What's wrong with the factory horn?

 

It's so weak that if someone has their window up and does something stupid they don't hear it. The stock horn on my supermoto is louder than my Tacoma.

 

I let my driving do the talking

 

Be thankful your horn doesn't sound like a 1st gen 5 lugger horn.
