    Default Could this burble be an Exhaust Gasket? Which part for a 1330 Motor?

    After running a couple thousand miles on my F3 with a Cat Delete pipe, She has started to make a "Burble" sound not a true backfire, when I close the throttle.
    Possible exhaust leak?
    Do I need to change the gasket at the joint of the cat to the exhaust pipe. If so can I use a Honda gasket as in the 998 engine?
    What gasket have you used?

    Thanks, David C.

    Some folks wrapped the outside of the joint with aluminum foil before installing the clamp.

    We've not had the donut seal fail on any F3 model since the first 2015. I did notice that an aftermarket cat-delete pipe had its mating surface not formed correctly with the sharp edges of the flared-only end rubbing on the seal. (I cut that one off and welded on a properly formed end.) Lamonster Garage pipes are done correctly.

    Our Spyder has run a Lamonster bypass pipe since they first came out.
    Early versions were a bypass pipe on, and no baffle to insert if desired.

    That said, after about 100 miles, the engine computer got the fuel trims settled in.

    FWIW, we have no exhaust leaks, run the oem 2014 RTS muffler.
    On deceleration for years we get an off throttle burble just a bit above idle as the Spyder slows, and downshifts.

    No loud pops or bangs, simply the computer is transitioning the fuel flow zero fuel flow, and introducing small amounts to keep it running as it gets to idle rpm.

    Not saying that is what you are experiencing. You did not mention running a baffle or not.
    If running a baffle, maybe the bolt came loose or fell out.
    Assuming your burble was not there previously.

    I run a cat delete pipe with no baffle and stock muffler. Mine seems to have developed more popping on deceleration and will check for an exhaust leak but I doubt it. I kinda like it as it gives the bike some character.

    Thanks to all respondents.
    I have a cat delete with a baffle. I drilled a few extra holes in the pointed end of the baffle.
    I'm running the stock muffler.
    The burble happens with a closed throttle when I'm slowing down. No popping or backfire.
    If I crack the throttle just slightly open the burble goes away.
    I have to admit the burble sound is not offensive. After reading the responses to this question It seems
    closed throttle burble is a common condition.
    For the time being I'm going to accept the burble as character building.
    Thanks again to all.
