When I remove the cats from my bike, do I need to do anything to the fuel mixture or will the computer adjust it as needed? The tech at the dealer said I need a download or a tuner, but other people say you don't. I don't have a tuner yet, but will get one soon, but want to remove the cats asap. Also saw where some people are drilling the cats out with a 14" long coring bit. Then you don't have to cut and weld the headers. Any one know anything about this? Am I better off to cut them out or does drilling work just as well?
Thanks
