    FMF power core too much noisy

    Just throwing this out there in case there are any recommendations other than stock muffler.

    I bought my TW from Oregon (OSU) MSF course - lot of miles but runs well. Has FMF on it, I have no idea why but it appears they put them on all of their trainer bikes. Way too loud, I bought one of the quiet core inserts but it is still way too loud for me. I don't know if/when it has been repacked but will take it apart and re-pack it, are all of the packing materials the same or any that might have a chance to make it quieter?

    THanks

    I much prefer the stock one. Very stealthy!

    And still amply audible, even at idle.

    The tighter and denser the packing material is installed then supposedly the quitter the sound level.

    You can use wall insulation fiberglass, to test the sound reduction, but it will burn out rather soon (few weeks of daily ridiing)

    Leave it to Fred to give a real answer The packing you showed looks great. At some point I will need it in my DG pipes. Thanks.

    A more permanent solution might be to find the stock exhaust listed on Ebay. When the stocker arrives, put the FMF back on Ebay and probably get your money back, maybe a little more.
