    Default Stage 3 103 2-1 discs

    I have a SE stage 3 103 kit. I have put together a 2-1 supertrapp header with an aluminum racing series universal muffler (4" external with 2.5" inlet).
    Can you suggest a number of discs to start with, so I can safely ride to my dyno tuner.

    Hi again, I just fitted this pipe up, finally, and it runs well but extremely hot, 18 discs as suggested. I should have asked the frst time, but open or closed end cap?
    Cheers.

    Unless specified we assume a "closed" end cap that is supplied with the exhaust.

    If you feel it is running "hot" due the A/F ratio being lean, reduce the number of discs by 2-3.
