Can someone tell me if the 2010 FX450 and FE450 share the same exhaust system, particularily the muffler? Looking at an endcap upgrade from barret exhaust for my FX but they only list FE's....
I just purchased a FMF 4.1 for my 2010 fx450 and their part numbers are the same. The install took 10 minutes, it fit like a glove, much lighter, more/crisper power. downsides are $400 and much louder. I only rode it on the MX track so the louder sound wasn't a problem ( with the stock I could barely hear the bike). I will try the quiet/ spark arrestor insert soon.
