    Default Atk 605

    I have a 1999 ATK 605 with the stock muffler, which I believe is the 4" race muffler.

    Is there a quiet core type insert available for my particular application?

    I've repacked (which helped quite a bit) and I'm running 8 discs, but would like to get it a bit quieter if I can.

    Quiet core assemblies for the 4" Aluminum Racing Series are NOT available. You may want to try removing a disc or two; however performance may suffer if you choke it off to much.
