Blowing your air horn when leaving. What do you want man?

I wish my coach had an air horn....
I wish I had the money to install Hooker Headers and stainless steel dual exhaust with glaspaks. I bet that V-10 would rumble nicely. Maybe 4 inch straight pipes would be better.
Outdoor speakers would be nice, too, so I could entertain the entire campground with my Spike Jones recordings ("My Old Flame", with the sirens and gunshots! GOOD stuff!)
But then, I'm not quite 75 yet, still in my second childhood, I guess...
