ive been wondering about the o2's myself, every one says un-hook them but even completely stock when i did i would get a pom pom on de-cel that i never got before. i haven't rode enough since i put the thrush mufflers in to know for sure, but on short rides they don't pop. my muffler guts were really sooty black too, i wonder if un-hooking the o2's were making it too rich. i'm going to run it with them un-hooked for a while longer and look at the plugs.
