Loud but poorly designed
I installed these on a 2022 SLR. Install was a pita mainly because of the Slingshot's hood opening but also because of the following. The new horns have a poorly designed wire harness. The original horn's plug is located next to the original horn but the new harness has equal length leads for both horns. They should have shortened the lead to one of the horns. The more serious problem is the new left horn hit my air filter box and couldn't be mounted without relocating the hole in the bracket. The bracket is flimsy and much care was taken while drilling. The horns themselves are very loud and I would recommend them with caution.

Tooting your horn
Upgraded from the stock horn to the dual horns by Slingmods, went from 65 dB to 110 dB an appreciable increase in volume. Look good, good quality and easy to install.

got-r-done
no doubt a 74 year old man who stands 6'6" will have some difficulty getting in under the hood, but i got-r-done. what a major improvement.
