So I went with these Hellas which cost a fortune to install because it involved removing all sorts of stuff (or so the dealership claimed), and I'd swear they're no louder than the lousy stock horn, although the tone is much more pleasant

2008 chevy 2500HD install was very easy, I did have to replace the stock connections, standard female spade, for the new horns.

My stock 2000 CRV horns were rusted out, so I opted for an aftermarket choice

I honestly don't think there as loud as the stock horns I replaced

when I honked they clearly couldn’t hear my wimpy mazda3 stock horn and proceeded to run me off the road

Definitely recommend if you hate your crappy stock horn

way louder then stock and easy to install

My SECOND set of these -- the first to replace the wimpy stock horns on my '07 MINI Cooper S, the second for my '03 Subaru Outback

Seems just as loud as the stock horn on our 2011 Fusion

Much louder than stock on both vehicles, but not sure if they are much louder than modern stock horns

The stock ones sound nice but these have way more punch in them

This product is almost as loud as my stock horns on my ford F-150

These are louder then stock in an unpleasant way for the person being honked at, however I was hoping for more.

Much louder then the stock horns
