I took the OEM ones out, replaced them with Bubs Stealth baffles that I wrapped with some 1300F ceramic fiber stuff.
2000 miles later, I'm decide to take them out. Fiber tape is gone, have some melted copper wire bunched up down the outlet end (I used it to wrap them), and a pair of baffles. that seem to be in good shape.
I put the OEM ones back in, and I'm happy. Not much louder, but there is a performance difference.
To remove the OEM baffels, I beat the crap out of some rigid aluminum conduit (thinking it was standard, until the first hit, then decided to hell with it, I have no other use for this piece of conduit) - that I smashed flat, dremel'd off on corner, then bent it around nearly back on itself.
Makes a perfect baffle remover-tool, but only for the OEM baffles. Too big for the stealth baffles...
BTW, I found re-assembly 10x harder than disassembly. Those damn heat shields don't want to line up with the extension and the hole for the tip...
