250-500cc WR250 Exhaust question

Hi All,

I've been looking at getting a fmf gnarly expansion chamber and can find ones that state they will fit 2000 - 2006 or 2009 - 2012.. am I missing something or shouldn't there be any difference between years? as I thought these motors had been the same for years??. While on the subject of exhausts would I be right in thinking that the gnarly is the best route for good bottom end pull?

Many thanks in advance!

Best wishes

Myles

I believe they are in fact all the same. I've got a 2008 w/Gnarly and Power Core.

Older one's probably specifically made for the WR250 while the newer one was designed to accommodate both the 250 and 300 motors.

Thanks guys. I thought that would be the case.. it's odd that it jumps from 2006 to 2009.. Don't they think us 2008 owners want an exhaust!!

I have an older (04) Gnarly that we compared to a 2013 300 and one of the mounts was in a slightly different place.

I agree, the front mount is off a little. I red rolled the pipe mount to get it to fit.
