Do you need to run a different plug when going from a DCS6421 cat muffler to a DCS6400(1) non-cat? Or is there anything else I should know before swapping these out?Can't say I've ever seen that before lol, what kind of plug does that thing have in it, a standard plug? I've seen saws blow fire on start up, but never every time you throttle up lol
