    My mufflers have holes in them. Looking for aftermarket options. Nothing that is too flashy or different from the OEM. What do ya'll use?

    Did you by chance do this yourself or see it in person? Are you familiar with how much fab or altering is needed?

    I have seen it , from what I know they should slip onto the collector, a bracket will need to be fabricated to mount to the footrest bracket.

    these are from much earlier in my build but had the best angle on the mufflers

    The rear foot peg brackets mount up just fine too, I installed those after those pics

    I also really like the sound, louder then stock but it still sounds stock.. if that makes sense

    @Noahsxj those look great. I'm doing some searching and those look like the OEM mufflers. Maybe I can get a pair off someone who upgraded.... Would you mind posting some more pictures of those with the foot pegs mounted up and all?

    If you haunt your local H-D dealership you might find a skip full of take-off mufflers around the back.
    H-D owners like fitting louder ones, and the old ones have no real value. Which is great, as we can use them.
    I've got a pair of Dyna mufflers on my XJ9 and I'm quite impressed by the build quality of them.
    I also used another Dyna muffler on my GS when I was setting up the Delkovic system.

    @Noahsxj, curious about how you mounted the mufflers to the frame. Any issues there?
