Cat Converter Removal
I built a 2 in 1 exhaust for my 1100. I attached a muffler from a 1300 and removed the cat converter. I attached the muffler to a bench, hooked up a 1 1/2" dia hole saw attached to a 12" extension on a 3/4" drill and chewed it out completly. It was a bitch to get out. My bike has carbs, so I had to perform some adjustments on the PMS and re-synch. The muffler does not appear to be all that efficent. If you are looking for a HP boost you will not find much. If you are looking for a better sound, I think there still isn't much advantage. If I were to do it over I'd buy a performance pipe.
