DIY: Old School Beep-Beep Horn Install (not airhorn)
I love everything about my 997, except for the OEM horn note, which is a combination of a 412 Hz and 355 Hz horns.
IMHO, the horn note sounds like a Chevy Citation or similar, not an iconic supercar, so I thought it would be "charming" to fit a proper retro sounding beep-beep euro-horn.
I found such a horn at Summit Racing of all places, and it is plenty loud at 116 dB, and sounds like a VW/Porsche horn of yesteryear:

The Hella part # is: HLA-002768082
As shown below, the two horns live behind the front bumper cover or fascia. I note that this is the plastic cover over the bumper, not the bumper itself. Some folks refer to the fascia as the bumper, anyway.........
To remove the front bumper cover, I refer to the thread here-I printed out the following instructions and followed them closely:

I want to emphasize that this job is not trivial, but not hard, but rather time consuming, and best performed with a friend to help. Start early in the morning. Use the proper jack and failsafe jackstands for safety. Also, there are alot of screws, so use a cupcake pan or similar to keep them sorted......
I have retained the photos and text on my computer in case they ever get deleted, so PM me if they do....
After removal of the bumper cover, you will see the horn bracket and the two horns, as shown below.
What you want to do is swap out the OE 400 Hz horn for the Hella disc horn.
The OE 355 Hz horn should be moved to the back position and the new Hella horn to the front. Double check fitment of the new horn by placing the air intake/fasica back on, and adjust horn mount as needed. The fit is tight, but I assure you, it will fit ! You may need to affix a piece of foam or rubber onto the air intake where the horn body comes close. This will prevent the horn body edge from rubbing on the intake due to road vibration.
Also note that these disc horns must vibrate like crazy on their brackets to work properly and thus must hang off the supplied specialty horn mounting bracket.
Wiring: OEM connectors are specialty, a a hybrid bullet type. Very sano. However, I could not locate aftermarket connectors like the OEM style. Instead, I retained the OEM connector, and used wire taps into the stock wires. From the wire taps I made little jumpers or pigtails terminated with female blade style connectors. The Hella horn uses male blades. The connectors and taps are easily obtained at Radio Shack.
As shown below, I share a picture of the horn installed.
To finish the job, just button everything back up as per instructions, or install stainless radiator grills as I did, which is the subject of another DIY.
