    What are the torque specs for the exhaust clamps on a 2008 sporty xl1200l seem to have an exhaust leak from that area.....would that also cause the exhaust to back fire? also what is or is there a torque for the header clamps?

    someone will chime in with the correct torque, and yes, loose clamps will cause it to backfire.......

    Recommend you get the service manual for the Sporty, all spec's will be listed.

    I agree with FLHTbiker. A repair, preferably a factory, manual is the first tool you should get for your bike. It will be the most valuable and used tool you will own. Until you get yours my Dyna book says the studs in the head, done in three steps, finger tight, 9-18 in-lbs, then 60-80 in-lbs. Please note the spec is in-lbs.
    Muffler clamps 45-60 ft-lbs.

    Replied on your other thread.

    get some copper silicone
    coat the inside of the throat of
    the muffler that slips over the header
    about 1 to 2 inches in

    Slide over the header and
    then torque the clamp

    I've had to remove some mufflers that were just simply welded on it seems like. Have taken a propane torch to the muffler where it connects to the header pipe and heated it up to help expand it. Never used copper silicone on em but if it seals it up and glues the pipes together no thanks.

    no it doesn't glue them together,
    it provides a seal and it wipes right off

    without it you are fitting steel to steel
    and hoping for a secure leak free area

    The copper silicone is designed for this
    and will keep the exhaust from leaking.

    In fact the muffler will come off easier
    using it....

    BTW next time vs heating the muffler
    take some WD-40, or silicone spray
    and spray around the lip of the muffler
    you are trying to get off the header.

    Give it a few minutes and it will
    penetrate and generally come right off

    Been there done that with the penetrating oil. I'll have to try that copper silicone, thanks for the tip.

    sometimes I resort to
    Harleys tool number 593510-99
    Harley Davidson Slip on Muffler Removal Tool - required when removing stubborn or
    stuck HD stock mufflers from the headers for service. This tool has been specifically designed for HD to work on HD and aftermarket mufflers for HD motorcycles. Use of any other tool not specifically meeting the requirements of the Hardley Davisdon company may void the warranty on your muffler bearings... Comes in HD Orange or Basic Black
