When we were kids, we used to go to the boneyard and get gasoline tank filler tubes and caps from old cars. We'd cut into the head pipes and install them, one on each side. The filler caps would twist on or off with 1/2 turn and would work great until the hot exhaust burned the rubber seal out of them. If you were really cool, you had a chrome filler cap showing right behind the front tire on each side.
