I am looking for an exhaust and since the 06 exhaust had the cats in the muffler's, if I add slip ons then it is basically a full exhaust.....isn't it? I don't mean that a 1500 dollar header and full exhaust won't flow a little better than it but is it close enough to save the cash and spend it elsewhere on the bike? If it isn't even close then tell me so and why. I have research it a bit and can't find much about it so I am guessing that it is a flawed exhaust and everyone junks it in favor of a spendy unit.
also, where are the o2 sensors if the cats are in the muffler's?
do I need to delete them if I remove the stock muffler's and add on an after-market system like the yoshi r-77?
thanks, any help would be appreciated.
