The horn on my Savage is pretty weak (like most I suppose).  I would like to replace it with something much louder.  I had no success in finding any documents describing the process (from removing the old one, selecting a compatible horn, and installation).  Every time I do a search on "horn", I end up with a ton of posts with "buckhorn" in it.

Anybody have experience with this and want to share some insights?

The problem is that most bike horns sound much like the one you have already.  Look into a car horn similar to one of these.

I picked up a pair like this for $6 at my local Harbor Freight and used the one oriented like the one on the left so that the horn opening is at the bottom of the curl (so as not to trap any accidental water) and facing forward.  Just take a look at your local auto parts store, Harbor Freight (if you have one) or even JC Whitney.  A car horn will get folks' attentions much better than something from a Roadrunner cartoon.

How does one remove the stock horn?  I see that there is a bracket held on with 2 large screws.

I replaced the 105db disc horn with a 138db blaster:

I now sound like a large car rather than a little bike.  I need to add the high tone mate to sound like a Caddy.

It just about mounted in place of the stock disk, using the extension bracket that came with the horn.  I may have used a longer bolt.

Here's a thought:

This is a Stebel Nautilus, supposedly the loudest horn you can get.  I'm putting one of these in my car.  Not sure where I'd hang it on the bike.  Supposed to make it sound high-pitched and annoying like one of those Italian sports cars.  Gotta do something to combat all those starry-eyed twinkies with cell phones and Range Rovers.  

RideSafer.com has a pretty good selection of regular and disk-style horns.

I'm pretty happy with mine right now.  At the moment it makes the bike sound something like a '74 Impala.

The link DavidV posted was to compact Italian air horns with an equally compact compressor.

WD,

Here's one, since you want to go really big:

A guy from my last office had a set of ship horns on his truck.  Way loud enough.  Loud and a much deeper tone than regular auto air horns.

And these guys make'em for ferries:

Not sure how you'll get these things mounted on a bike, (or if you'd really want them so close to your own ears) but I'd love to see it.
