I love everything on my 07 QP... everything except the horn.

I had the same problem with my F40, so I replaced the horn a few years ago with a two-tone air horn. Now she-ah sound-ah Italian!

But before I start removing engine shroud, where is the horn located in the QP (not the horn BUTTON, the actual horn).

From the looks of the parts diagram, it appears to be dead center behind the front grill (under the Maserati badge).

How would I get my OWN copy of a parts diagram?

I too would like to replace my QP horn. Such a unique car deserves something more special! Please don't think it trivial; my question is, what would you Masi owners suggest, and in particular, what would an Italian want? Where can such a horn be sourced? Thanks in advance.

Thanks! They warn in the description they are loud. Would you or anyone else know how loud?

no Clue

They also have the Hella electric horns. They are LOUD. At least 2 - 3X louder that the horn in my coupe. I have not heard the air horn before. Cal them, they have always been very helpful to me. If it sounds like the horn from my 355 I will get one. I think the car needs something that does not sound like it came from Detroit.
If you did not know, decibels use a logrythmic(spell) calculation so every ten decibels you can count on the sound doubling in intensity.
20dB to 30dB = 2x
20dB to 40dB = 4x


Here is what the description says:
"139 dB at 4 feet, 115dB at 6 feet"

I found this link that puts things into perspective. 115dB is somewhere between a power saw and pain.

In sourcing an Italian horn, I came across the Stebel S.p.a. website that manufactures the Nautilus airhorn. For those interested it has an audio clip of the sound.

Has anywone actually made the mod? Reading on other forums, there was discussion about having to change to a larger fuse. How difficult is this to do, and would it affect warranty?

Thanks.

I did this mod on Saturday. Used an Italian-made Stebel GP2 horn kit. Had compressor, bolts, horns, and tubing included in the kit.

Remove the front grille, remove the black plastic shroud, then remove the horn bracket and unplug.

Mount the trumpets to the existing bracket. Splice in spade-connectors, connect the compressor, then mount it to the underside of the lip next to the right-side trumpet.

No drilling required, and only one wire cut (I wanted to use the existing horn wiring harness, so I crimped spade connectors onto it).

Horn is WAY louder, and way more Italian.

P.S. I did this same mod on my F40 three years ago.

Thanks for the instructions. I was looking at the compact horn, but your description sounds like you used the dual horn kit. Is there a difference in the sound? Do you see red horns through the grill? I take it you didn't have to change any fuses etc. When I googled the horn kit, I saw your post on the Ferrari site, but unfortunately, the .jpg images of the installation are no longer available. Do you still have them, or did you by any chance take any of the Maser?
