the F11 also had the MES exhaust.....as I say nothing has changed.....
edit... with RB who knows, they have multiple sleeves they use in these fire series engines.....I have cycled thru a couple dozen of the F11 engines and every one of them has had a MES exhaust....however the first couple engines had a different style MES sleeve...but only a couple, the rest have the same sleeve they show on this latest version............
