coffman rocket pipe B1

Hey guys I have a guy that wants to buy my coffman rocket pipe for his B1 but he is concerned it is a dry pipe and wont be allowed in sport spec if he chooses to race it. The pipe does have water jackets to cool coupler areas but it does not have adjustable injection like a bpipe. I have never ran a true dry pipe but from what I have seen they have no water lines at all and are a single metal chamber...just want to double check this before I sell it to him
