    Default 1986 Yamaha XT600

    I have a Supertrapp on this bike from previous owner that looks like it has been modified with just an open piece of piping coming out of the back. The # 027-2843 is printed on the pipe. How should this pipe look and can I buy the stuff to return it to normal. If not will a 027-2858 work, as I have been offered this from a neighbor and it is intact. Thanks for any help.

    Neither one of the muffler body part numbers are in our data base any longer, which is pretty unusual. So, I do not know what you have; however if you can provide pictures of both I may be able to tell you what "Series" and assist you with obtaining components you may need.
    Do you have a connector pipe? If so, can you find a P/N off of it for reference purposes.

    Hopefully I have added some pics to this reply so you can see what I am talking about. The pipe attached to the muffler has no numbers that I can find.

    It appears you have a 4" Aluminum Racing Series muffler where someone has replaced the disc assembly with he tubular end cap, as you pointed out..
    A disc assembly (screws, 6-12 discs + closed end cap) could be attached if the 6 receiving nuts at the end of the core are still intact.
    We offered two slip-on applications for the XT600, model years, '84-89 and '90-94 (both discontinued in '04).
    I am showing one of the s-bend ('84-89 connector pipe), P/N 048-217, still on the shelf. If the inlet on your muffle is 1.75" and your XT is an earlier model it may work; however...
    Will the bracket line up or would additional mods need to be made?
    Replacing/restoring the muffler disc assembly and/or s-bend may be cost prohibitive?

    Default thanks again

    If the receiving nuts are OK is there a specific # for the end cap and discs? Thanks again

    Is there any setup you would recommend for a Yamaha XT 600 43f -84?

    The 4" Aluminum Racing or IDS2 Series work well on medium to big bore thumpers.

    Red face help

    I have an 86 xt600 and I recently came across a supertrapp slip on. But what I don't have is the connecting pipe . You know the one that connects the head pipe and the slip on. Can anyone help.?

    We no longer manufacture (discontinued in '04) an application for the XT600; however we do have a couple of s-bends (connector pipes) still on the shelf, P/N 048-2017. Check the P/N stamped on the back of the welded on bracket of the muffler. If it is P/N 027-2241 or P/N 027-4598 the s-bend complete the system.
