   Ducati 250 350 450cc Replacment Exhaust Sleeve for bikes with stripped out exhaust threads. Sleeves are installed by machining out your old threads and pressing in this sleeve. The outside edge of the sleeve is secured to the head by wielding.These improved exhaust sleeves have a flange in the bottom so tightening the exhaust nut doesn't pull the sleeve out of the head. Much stronger than straight thread type of replacement sleeve. If you need some one to do the installation of the sleeve we can highly recommend Ducati Phoenix.
