I have always had 50/50 luck with UFO, it either fits good or it doesn't, as for the one industries plastic it is the exact same as stock, on my cr the same markings and numbers are there, except where it says honda it looks sanded off:think
But talking to some "people" they say that ONE and OEM are made and the same place:D
what i was told was that one is just buying somebody elses and reselling it, which means that you get whatever they get the best deal on. who knows. my experience is limited to yz thumper stuff. last time i looked at their product, there was no heat shield and no metal inserts in the holes - both of which came on the ufo product that actually cost less!
