Will a 250ex stock spark aresster fit on a 400ex stock exhaust...

i dont believe so.

why would you want to do that anyways????? and no it doesnt

yes i have to agree.. that is a pretty dumb idea... but i will not work anyways

I think it sounds bad with the spark arrester out, it doesnt really matter cause im getting a new end cap...

yea the 400 with spark sounds like poop on a stick

Many riding areas require a spark arrestor.
