The horn on this car is the one thing I'd like to change. (ughdance) You can get aftermarket lights, radios, etc. Can one get a nice dual-note horn somewhere so the car sounds as serious as it looks?
 
Horn Upgrade

Just installed a pair of FIAMM Highway Blasters from Advance Auto (bout 16 bucks each). Got a high and low combination. Just have to play around with the position since it's a little cramp inside. Works like a champ and this should keep vehicles straight on their lanes. Aggressive looks now matches the growl(dance). Just in case, location is inside front left facia/bumper. Need to remove front left tire and protective cowling.

I never really realized how wimpy the horn was until after a week I took my GS home. I called the dealership and told them that something wrong, when I arrived, they told me there was nothing wrong....it really sounded that way. (whip)

I was hoping to replace mine too, but would it void any warranty on the electricals?

Any alteration from the original normaly can void a warranty. That was why I patiently waited for my basic to expire. Although changing a horn is not a big job (only one wire for one horn), any short can mess up other components. I disconnected the battery before I did this operation as with any electrical work.(mj)

where is the horn located? looks pretty tight inside, sounds like its buried on the drivers side, but usually they're located in front of the radiator, though I don't see it.
 
Tapping into factory horn wire for triggering shouldn't void warranty or it can be easily reversed. Besides, the cost of factory horns shouldn't be much.

I didn't shorten the air hose. The long hose gives me about one second of delay time. It gives a two stage effect. A quick tap only activates electric horns. Holding more than one second will activate (louder) air horns.
 
I installed a set of air horns.

Sometimes other people still can't hear.

I was looking for something louder than OEM, but a little more subtle....
Certainly one can get something that works that mimics the sound of a Bimmer's horn(??)

The horn is on the drivers side, next to the radiator, you're right it's a little tight, but if you remove the drivers side protective plastic in the front part of the drivers side wheel well you should be able to get to it without removing the front tire.....you'll want to raise the front of the car, or drive up on ramps..... I'm getting ready to install fog lamps, so I'll take some pic's of where the horn is once I get in there......
 
That youtube is really funny! I've always wanted a train horn. Sad part is that it's illegal (in the USA anyway) to have one. I guess you're not allowed to 'impersonate a train.'

You will be my hero for the pics and tutorial - I've decided to do this mod, but haven't been relishing going in blind.
 
I bought an electric pump powered air horn. I just did the work from below. Took the old out, added longer wire, bolted in the new horn and hooked up the wires.
