The second "stock" type, cowbell-mounted horn just crapped out. The stock horn died after 3 years and
I replaced it with some generic, $30 after-market replacement which just died as well.

I need to get some recommendations for an easy-to-install, REALLY FREAKING LOUD air horn that
won't require a lot of rewiring. I'm willing to relocate but I don't want to wind up with something that looks
like it was done by the Beverly Hillbillies..

Suggestions? Ones to avoid like the plague?

(pics would be really great..)

Thanks!

 

wolo makes a nice one

 

Pro Pad Mini Beast air horns. I have one on my SB, 128db... Its loud as F! Definitly wakes up distracted drivers, makes them think a Mac truck is right by them. Around $100ish dollars and easy to install.

 

+1 for the Wolo Bad Boy, also sold as Stebel Nautilus and a few other names. They can be had as cheap as $31 and usually include the relay. They also come in chrome for a few dollars more.

After moving to Atlanta, I put them on all of my previous bikes that had quiet exhausts. Really got the attention of cage drivers when needed. Note: Do not test in a closed garage without hearing protection!

That said, I haven't needed it on the Harley with its Cobra pipes, even with "quiet" baffles.

 

Another vote for the Wolo. They aren't perfect, and I'd advise covering it up with something before pressure washing (mine sounded like a duck for about two days after I didn't do that), but they seem to wake people up a lot more than a stock horn. And they're cheap.

Regarding manufacturer claims about how loud a horn is:
Depends on how they measure. Without knowing that, it's pretty meaningless. I measured several with a decibel meter under identical conditions. Even though some of the air horns aren't much louder than the stock Delco horns on my Chevy, they have a different, and somewhat more attention-getting sound.

Also, I've managed to run mine for a while now without the complication of wiring in the relay, after reading that some others had done so successfully. Maybe it will fry the horn button eventually, but it hasn't so far.

 

I can personally testify that the wolo horns if tested inside a building, will make your ears ring for over an hour!!!! You can see the chrome ones HERE

You can also get it in black from this LINK

 

Website for Pro Pad is around $200.00
Wolo kit around $70.00

 

Rivco is selling one for about 150 dollars on ebay. Says it is loud and comes in chrome and black.

 

Thanks everyone!

I wound up ordering a Pro Pad Mini Beast chrome from Amazon who had it $20 cheaper than anywhere else
and with free shipping.

I was really tempted by the Wolo but a significant number of people "rating" it on various websites claimed
to have had some problems wiring it or that the wiring kit didn't really work that well. I don't know if that's
true or if they were all thumbs, but it was enough to tip the balance in favor of the Mini Beast.

Thanks again!

 

Don't know how Wolo mounts, but Pro Pad is a complete swap for the stock horn. Just unbolt the old one, disconnect the wires, reconnect to the Pro Pad, and bolt in place.

It's loud as hell and looks good (IMO).
