Thanks for the replies, knowing the WR will not fit saved me 80 bucks. I have used the Pro billet application on other bikes, but do not have the stock exhaust and they don't make one for the White Bros. I will look for the insert. If anyone has a stock 06 exhaust laying around let me know. firstname.lastname@example.org
Is the stock 06 WR250F exhaust Forrest Service Approved? Need a cheap conversion for the bike, it currently is running a White Bros exhaust, not sure of the , but no screen or stamp. Moab in 2 weeks. What other years might fit. Thanks for the help.
