white bros e series

Does the white bros e series spark arrester that fits the 2000 wr400 fit the 2001 wr 426.

because i just purchased one for a 2000 400f for my 2001 and the header is much smaller in dia then the muffler pipe.

You have the correct unit - they are interchangable. There is a graphite seal that fills the space between the larger muffler pipe and the header. If you look in the stock muffler you'll find it. Probably won't be able to remove it without screwing it up - but who knows. Most dealers have them in stock (P/N 3GW-14714-00)

Thanks Mike

I seen that after further inspection that there was a seal and you are right I couldn't get it out so i will have to buy one.
