The last guy (on WR250Rforum.com) that claimed what you are says that filling-up with some fresh gas took care of his problem.
He may have drained the old stuff out, first, but I can't recall.

How does your air filter look?
Look inside the airbox, don't just peer in from the top inlet.

You sure something isn't stuck down inside your pipe? Dead mouse?

A leak in pipe at can shouldn't be a huge issue, but if the packing, or something else has clogged pipe you would get that.

Take the can apart.
That's where I'd start.
And the airbox is a good and easy place to look as well.

A member at another forum has had insane mouse issues with airbox.

Perhaps you have one in your exhaust canister?

Call FMF they will get you hooked up quick, called them for decals and such for my can when i made my undertail and had the stuff 2 days later.

find something to plug your exhaust when you wash it and replace your packing now, if its gotten wet its gonna be junk. its cheap get new.

Take the screen out of the end and turn it around,all that little pink fuzz you see cloged it up slowly over time and cannot be seen from the end looking into the pipe.
I removed mine one day to see how much louder it made the bike and was amazed how small the hole was. And how much better it ran after i cleaned it out.
