That's on my to-do list too.
I installed a Stebel Nautilus ultra compact air horn. Very easy install, no drilling on the car. At 70 mph on the highway with the top down, I could not hear the OE horn.
Before the install, I checked the sound level of the OE horn; 110 dB at the grill and 95 dB at 6 feet directly in front of the car. My meter scale only goes up to 120 dB. The air horn pegged the needle, waaaay passed the 120 mark, at the grill. I think the 139 dB advertised is reasonable. At 6 feet the reading was 105 dB, about 3 times as loud as the OE horn. All readings were taken inside my shop.
I can now hear my horn at 75 mph.
On the track, I am fearless.
If you were as slow as me, you wouldn't be afraid either.

I have the same horn, and I love it also.

Did you hook it up to a relay? I didn't and I think it should be louder.

No relay yet. I just replaced to OE horn with the Nautilus.
A post on the pointy board stated that since the brake lights and the horn are on the same fuse, if you honk while braking you will blow a fuse. So, I tried it, and blew the fuse. But, the fuse survived several short honks. I had to lay on the horn for about 3 second, holding the brakes on the whole time, before the fuse had its meltdown. YMMV
I plan on hooking up the relay sometime in the future. If the battery was under the hood, I would have wired in the relay during the install.

The Nautilus horn that I purchased from Thompson-Automotive.com actually came with a 20 amp fuse, ground wire and metal bracket. Here is a quote from their product description:
This horn comes with all mounting hardware (including a Thompson Automotive custom designed mounting bracket), a fuse upgrade and full installation instructions. The horn assembly mounts right where your stock horn mounts and uses the same connector. So it is literally "plug & play"

My horn came from Griots Garage. The instructions for my horn are to wire it via the provided relay and inline 20 amp fuse directly to the battery. I had to make my mounting bracket and ground wire. My instructions also said nothing about the air intake and dusty/wet conditions.
Thanks for the additional information. I'll put a 20 amp fuse in the glove box. If the 15 amp blows, I'll put a 20 amp in.

Anybody who hasn't upgraded their horn should definitely consider this modification.
My Nautilus saved my butt yesterday. I was sitting at an intersection in the right lane waiting to make my turn when a semi truck passed me in the left lane. He proceeded to make a wide left turn and I saw his trailer getting closer to my car (surely he'd stop). He "didn't see me" and kept going. I laid on the horn and by the time he stopped his trailer was probably 6-12" over the top of my car and something on his truck had torn my driver side mirror off (bending some sheet metal in the process).
If he hadn't hear my horn (glad I've got a Nautilus) the back wheels of the trailer would have easily rolled over the trunk of my car on the driver side. Don't know how I would have gotten out of that situation. I was blocked in and didn't have anywhere to move the car when this was happening.
I've also heard the Hella super tones are a good horn. I think Black Roadster has a set.
