Great fit on my 2016 cfr450x, take the baffle out and install a J D get kit and you'll have a great performing bike and super sound.

Perfect fitment on an 05 450x with a Megabomb header. Seat of the pants says it opened up the bottom end quite a bit and makes things a bit snappier. Closer to my R. Tail is shorter than OEM so less vulnerable to trail rocks, has quite a bit of bark but no louder than other aftermarket exhausts
