That was my thought, I only really see a need to hide it if used for street racing. And anyone with half a brain can spot nitrous nozzles and accessories. Doesn't seem worth it to me.
You can definitely hide an entire nitrous system, including solenoids, lines, nozzles, etc. I've seen people run nitrous lines through fake vacuum hoses... Horn-button arming switches... The list goes on and on.
Fun thing to do is install a fog light switch as the arming switch in an LX. Most people miss that.
I am on a couple of local forums and watching them negotiate $ races can be pretty funny. According to them, they all have basically stock cars that run 12's. This is pretty neat in my book..
