Must have upgrade
I was skeptical that this would be louder but replacing the 2020 Slingshot R single horn to the dual horn, with easy installation, was significantly noticeable. Lets just say I almost jumped out of the seat when I tested it expecting not that much difference. My partner was inside the house when I tested the horn after install and she even commented "That was loud". I just wish I never have to use the horn but we know being a low profile vehicle we always have to be alert and one step ahead of the other drivers.
Stay safe, ride safe.

Loud
It's a nice noticable difference

100% improvement over factory horn.
Replacing the passenger side horn was easy. However, I have a 2020 R with a cold air intake from **. The side of the air box was in my way so I had to mount the driver's side horn inside the air box facing upwards. I'm happy with my purchase. I got the horns for safety, not cosmetics and they're a definite improvement.

Well worth it
The new horns are significantly louder. Installation was a breeze.

Major difference
I was lil optimistic when I saw that these were identical to the factory horn so I was like why not just add another one, even the writing on them was the same. But when I installed them...MAN!!! These things are loud
