Cooney...dont make the assumption that the YZ450F headpipe will make it run better. I owned an '08 YZ450F and the low end is lacking a bit (compared to the WR) partially due to the size of the head pipe. So, while it may look cleaner to no have the FMF insert/spacer it may make take away some low end grunt on your WR.
So....i wouldnt spend alot for a YZ head pipe for your experiment.

Um not sure about losing low end with that header pipe. I run them on all of the WR's. But they are pricey.
