I did this mod to my ’99 VFR. Read a few posts and many said that the heat from the exhaust pipes would melt the horn. I can report taht after one year, riding in summer, iddling a lot in traffic, it still works perfectly, and no sign of heat stress.
I bought the Stebel Nautilus with a wiring kit on eBay from “onlineautoparts”, $56 delivered.
Only place that it fits, without modifying any of the fairing, is down low. Has the advantage that the sound has a clear path out through the front of the fairing.
There is an unused engine mount just in the right place. It is around 9.5mm, so I ran a 10mm drill through it to bore it out. Had to unbolt the radiator so that I could move it slightly aside to get at the hole and a socket onto the bolt.

Went to Bunnings and bought a small length of aluminium bar and made up a bracket. Had to put a slight bend it in to curve it in slightly. Made the bracket slightly longer, drilled a small hole and used it to tie the cables in place at the bottom of the bracket.
10mm bolt and lock washer to the engine mount, and used the Nautilus bolt and lock washer to hold it on the bracket – rock solid.

The end of the trumpets look close to the headers, but I can put my fingers between the plastic trumpet and the header, it is no closer than the inside plastic fairing cowl to the headers. The main body of the Nautilus is well away from the headers, and the whole unit will get a good air flow past it.
The wiring kit came with the cables in a black sleeve. Perfect length, ran the cables up to the frame, inside the frame to the stearing head, across in front of the steering head and out on the left hand side by the radiator.
I was able to unplug the wires to the OEM horn, pull them up and re-route them to the same location, you can see the blue connectors I used to bridge to the cables for the relay.
Mounted the relay using the ignition coil (plenty of room inside the fairing and should stay dry) and ran the relay earth back inside the frame and used one of the brake line bracket bolts, just next to the steering head to earth it to the frame.

Wiring kit also came with a n inline fuse for the 12v supply to the relay. Ran that back directly onto the battery. Cable length put it just above the rear cylinder head, where it gets hidden by the front edge of the seat when it is in place.

Sound. Nice and loud, don’t use the horn often, but when I do I like them to take notice. They will see a truck but not a bike, same with a horn, they just won’t hear a bike horn.
