    Muffler build now i could rip my hair! (if i had any)

    FINALLY! The day had come when i have all the new stuff for my bike.

    I have done the muffler on my own from a XB9 that i bought cheap.
    I have collect all the info i could (txs to this site)

    The info iŽll been told are that they are all the same, except from the valv.
    But now when i gonna put on my modified one the exhaust intake are so different in size.

    My XB12 has an inlet of 63mm and my modified XB9 is 50mm.
    Its also looks like the angle is different.

    So heres the dilemma....

    Should i modify my original muffler or try to fit the XB9......Muff01.jpg Muff02.jpg

    I've heard the export bikes are different. Not sure how true that is.

    Are you in Sweden? What are the odds?

    I’d heard also what Outlaw and loonyticfreenj said.
