The best fix is the International bellowed uppipe kit (doesn't use the stupid donuts). It is rather expensive for the OBS trucks at about $800. Some folks have massaged (slightly expanded) the uppipes so the donuts fit a bit tighter or used the brass donuts that are (were) available from Beans Diesel Performance (BDP) with varying degrees of success.
