Alright, I finally got mine installed and working correctly. These things kick ASS!

The sound vibrates the whole truck.
A few things:
You'll need a 3 gallon tank minimum. I bought a 3 gal and its good for a couple good beeps. Anything smaller and it will empty out too quick.
Get some high pressure line. Mine blew a hole the first time running up the tank. I ended up with 2 10' braided stainless hoses from home depot that are good for 1400psi. The SS will help with the heat in the engine bay, rubbing on whatever, etc.
So far they are a lot of fun. I scared the **** out of two kids who thought they'd be funny and play chicken with me. Those kids jumped to the sidewalk and wiped the smiles off their faces REAL quick!

Now the fun begins....
Highly recommended!
