I know what you mean! One of the first things I did when I got my 300SL was to fit a couple of Fiamme air horns just inside the front grill. No additional relays fitted - I just paralleled the Fiamme air pump across the existing horn wiring.

It has the added benefit that if you just "blip" the horn, only the original "frog" horns operate, but if you really want to let someone know that you're there and keep it on a second longer the pump pulls in and you get a great sound

Even in the over regulated UK I've had no problems with car tests etc. as it's just one "blaaarreee!" rather than the (illegal in the UK) dee -dah - dee - dah type

cheers
