FMF Powercore

Has anyone put the FMF Powercore slip on, on their YZ250F, if so how do you like it? Did you have to re-jet your bike? How is the power delivery...as in did it add any top end? Thanks in advance.

I am also wondering the same but for a 02 WRF 250

I have run one on a YZ250F before, as well as a YZ450F. In my experience this pipe just mimicked the stock power. It is a little lighter than stock, but power wise it is pretty much the same. If you want power gains go with the Factory 4.1.

is the power core louder than a stock YZF exhaust. I have a canadian WRF so doing any mods to my system is prety much out of the question. I mostly want louder than what it is. looking at a YZF system or if I can find a cheaper aftermarket system I might go that route.

And one more ?. is the DR D a nice system. sorry for jacking the thread lol

i ride a 03 wr with the dr.d system and it has a extreamly powerful mid. it is a little loud though. IMO its awsome.

I put one on my 06 WR 250 with an accelerator pump (Boyesen) and the results were wonderful. Top end, not sure but much better power thru out the powerband.

Thanks fellas for the info.
