We are in process of ordering several sets of "no number" unstamped exhaust pipes from Japan. Somebody over there has an inside contact at Honda's exhaust sub-contractor and takes pipes off the assembly line before they get stamped on them the politically correct (and for us, incorrect) paragraphs, HM300 lettering and brake pedal indent. Apparently, these have been sporadically available for a year or 2. Back-door pipes I call them. Exact price will depend on how many we buy at once. They cost nearly double than a new normal factory set from Honda (list $1000 +-) but a quantity discount will save a considerable amount. Lets have a "show of hands" from members ready and willing to commit X amount of $ for this. Nobody makes any profit from this other than Japan supplier. A sample set is enroute soon. Somebody in States already has a couple of sets, nobody I know has seen them.
