When I fitted my Scorpion can before Ivanising, I noticed a definite performance improvement when the baffle was removed. Since Ivanising, I haven't refitted the baffle to see if it changes much. I've always looked at the induction/carb/exhaust as a single set up and believe if you change any one part, the rest ought to be altered to match FOR BEST RESULTS. Which doesn't mean it's always absolutely necessary. A freer flowing exhaust (well designed) means better scavenging, and I think can also help to draw in the next charge from the carb side. The full monty set-up really needs an effective exhaust to work at optimum from what Mike has told me, due to up-jetting and air box mod. I would guess that fitting the baffle would reduce this effect somewhat, but TBH, I've been reluctant to mention anything on this thread when there's someone as knowledgeable as Mike around! :lol
