This is probably old news for most on here. Those that have the FIAMM horn(s) usually do a direct swap with the factory horn and just bolt on the FIAMM choosing either the low note or the high note horn. I wanted both. I just like the sound of harmonies. Anyway, I posted some pics and a short video for those interested.

Link to the images.
