They have a option for "OPEN" pipes. I haven't decided if I'm going to add cut outs but if I do.......it's a definite add on. I didn't see one for "EJECTION SEAT" or "SHUT THE F**k UP" so those are out.
I say don't label them. It'll be more exciting to just guess. If you're like me, after you don't drive it for a while you'll forget what all the buttons do :D
