Replacing stock horn with an air horn

Replacing stock horn with an air horn
I'm thinking about replacing the stock horn on my MY09 GTS with a Hella Air Horn.
I know it sounds cheesy, but I hate the sound of the OEM horn (sounds like a Buick IMHO!), and the Hella Air Horn sounds great! I have a Hella horn in my 911, and I love it.
Does anyone know how difficult it is to access the horn and replace it? I did a search and found nothing on this subject.
Thanks!

i replaced both my standard horns for electric air horns.
if you have a cayenne or S its easy, if you have a turbo its a bit more aggro.
because there located eather side of the car just behind the intercoolers.
you can access them from underneath by removing the front wheels and going up underneath the wheel well lining.
its so worth it because she now sounds like a train.
good luck.

Do they need any additional wiring etc for the air horns or are they a quick, straight replacement?
Do you have to remove the wheel well lining or is it possible to get at them without removing it?
Thanks.

as long as there not drawing too much current you can just fit them as a direct replacement.
if there a bit "heavy" you might need a relay.
ive known people get to them by just removing the undertray and others need to take out the wheel liners.
change both of them for max results

Wow, I had no idea there were two horns!
Is it possible to replace one and simply disconnect the other? I feel that two sets of air horns might be major overkill! Typically air horns systems are dual horn (trumpet) anyway.
What is the “undertray” that needs to be removed to access the oem horns?
Does anyone have any pics of this?

yes you can just replace 1 horn, but why?
porsche use the high/low frequency horns.
my electric air horns were only a bit bigger than the originals (look like a large snail )
the undertray is under the engine front (covers the sump etc) when thats removed you can just get small hands up to access the horns (cayenne and S)
turbo is better done through the wheel well liner.
dont forget to point them backwards or downwards so they dont fill with water etc.

anyone have good example of horns that can be easily switched with no relays?

obviously a bit obnoxious and not a simple replacement

Thanks!
Do you mind telling me which air horns you have?
I have a GTS, so I assume it's the same install procedure as the S, correct?

Is this easy to remove as I now have 2 new horns to install. Any pictures would be great...
As I have 2 horns to install, do not fancy removing both wheel liners..

Does anyone know if these Hella Dual Air Horns will fit in the location of the stock horns (on both sides)?

With a total of four "trumpets" my Pepper's horn is going to be LOUD!!!

I haven't messed with the Cayenne but have installed air horns like this on few other cars:
http://www.amazon.com/Stebel-Nautilu...=pd_sim_auto_2
They are LOUD! And much easier to install if space allows it. The delay is noticeably less than the traditional air horns with tubing too. Relay & additional wirings are must for most modern cars. (I have only seen older european cars that come with factory air horns.) Otherwise you are guarantee to pop a fuse.

why too large? you could fit an elephant under there if you wanted.
just make up a bracket and you might have to extend the wires a bit?
fit any horns you like, my 2 electric/air are about 3 times the size of the OEM ones.
and 3 times as loud

I fitted the new horns via the wheel arch covers. A little tricky to get at the wiring connector and the short length of wiring to the horn, but got there in the end. I did not go big horns though, just new and better. Just a little louder.
