Hi
They are quite a lot louder than the originals.
I fitted them a couple of weeks ago having bought them second hand & have done around 300miles with them on.
To be honest I prefer to be able to have a conversation in the car without having to raise my voice & as I have the kids in the back most of the time they aren't really suitable so the originals are going back on. They do suffer from some in car drone around 2 -2300rpm, dropping the window a little cures this.
Just don't suit my style of driving to be honest
