Have a cousin who used to have a '70 scout when he lived in Kentucky. It had straight pipes with no mufflers at all. Ran it like that for a long time.
Well that doesn't mean it was legal. There's a big difference between open headers and straight pipes too. I would dare say that it's not legal to run open headers in any state. Even if there's nothing saying you can't, I bet you'd get pulled over for it. You have to check the laws or call the cops in the state you live in.
