Plug and PLAY!
One thing we noticed before we bought our 2020 Slingshot R was the horn, The Plug and Play Dual Horn Kit sounded( no pun intended) as if it might solve the problem. It did. It took about 20 minutes to install by myself and it gives our Slingshot an auto-like two-note horn that it much more likely to bee heard. That's shy you blow a horn.

Easy to install
Only small issue for me is that I have the DDM Cold Air Intake. So the second horn placement had to be slightly adjusted. LOVE that it sounds like a car and not a buggy.

Easy to Install. Great sound
