Can any one help with Enhancements / Mods in Maryland (MD) ?

[Raza]

Hi

I am wondering if any one has tried enhancements / mods in their Leaf in Maryland. I would like the following to be done on my 2012 Leaf.

1. Change the horn to a better one

2. Disable the humming noise that car emits below 25 mph

3. Adding the word "Electric"

Anything else?

Of course, I am willing to pay if some one has tried on thier Leaf and if they can do on mine.....

Thanks!!!

Raza
