I actually broke the paddle bit and an extender. I ended up using a long wood bit I had laying around. I used a drill extender with a wire wheel for final clean up.
I think I heard of guys using a 3/4 or 1 inch spade bit. I would think the bigger the better. You know your not going to get all of the material out right? You would be better off cutting it and welding it up in my opinion.
Good luck !
Correcto mundo...you'll never clean the CAT out without cutting the pipe and then re-welding. I did my 2011 Ultra (and you can get it all out, just takes time and sweat) and it ran like crap, so I went to HD and bought new pipes (they sell 'em cheap as they are take off's from new bikes) and got it back to running correctly. Sold my non-CAT pipe on ebay.
