The best way to remove it is to heat the fitting it screws into with an acetalyne torch. If you don't have one find a muffler shop to do it for you. It will save you alot of aggravation, time, knuckles, band-aids, and cursing. If you try to "muscle" it out you may wind up taking the threads out with it. If you bring the new one with you they could also install it and they shouldn't charge very much. Have them use some anti-seize compound on the threads so it will come out easier next time. Don't forget to reset your lambda counter and check your valve adjustment. While you are there remove the test plugs and reinstall with anti-seize too. Whenever you work on the exhaust system heat is the only way to go!

I know it should unscrew, however it just won't budge one mm, Is there an easy way to do this, I've used penitrating oils and WD 40 to try and free it to no avail. > > Paul > > #6463 > > > [Non-text portions of this message have been removed]
