SInce i am theonly one here that is actually going to answer your question. Is the resonator acces. from one of the open ends? If so just get a long extension and take a big hammer and go to town on it. The pieces will start fall out like theres no tomorrow. If its not acces. from a straight opening you can just cut out the resonator and put in a straight peice from adavanced or something with a couple of clamps for about $20 or so.. hope that helps.
