While inpatiently waiting for my Thunder Alley to be shipped I needed to repack my stock pipe. I bought the packing (Moose... I think) wrapped it snugly, used masking tape to hold it in-place, reinstalled the pipe, and she sounded good again. Problem is, the packing lasted for two rides. I pulled the pipe last night and the packing was all but gone. Any suggestions? Who makes a good slide-on packing that last longer? Or did I just do a sh@$ty job of installing the wrap-around stuff?
