In have a 2011 FE570S, and the factory exhaust can on my bike forced the exhaust gasses through two 180 degree bends. I successively tried an increasingly aggressive removal of material from the baffle, and no matter what I did the can still choked the engine. I was very methodical, and tried to preserve the spark arrestor characteristics. No joy. Eventually I concluded that in order to remove enough restriction from the exhaust can to make the engine run like the engineers intended, I'd have to either remove the baffle entirely or remove so much material from it that it would not retain its intended spark arrestor characteristics. So I bought an FMF 4.1 Factory slip-on, and it's run like a dream ever since.
