terry Posted June 8, 2004 Report Share Posted June 8, 2004 I got the 2001 Beta and am in the process of going through it and one thing I am working on is cleaning the exhaust system. I have the silencer cleaned and ready to repack but my question is about the mid muffler. What is the best way to clean it? I am assuming that it has packing in it also so I am not sure if I can run a solvent through it. I have it off and proped by the shed now letting the oil run out of it. I was thinking of dowsing it in degreaser and blasting it out at the car wash with high pressure hose. What is the best way to go about it?

kevin j Posted June 8, 2004 Report Share Posted June 8, 2004 I have used solvents, heated int he barbecue grille, used the frayed cable and drill motor, but the best has been oxy acetylene torch on medium heat until it gets hot, then excess oxygen into the pipe. It burns it way back (up) slowly and does a great job. I think it was a tech article here or TA that I learned it from. HOWEVER, big warnings: Mine were steel, I would NOT do an alum muffler that way. Aluminum doesn't change color with temperature, just would suddenly melt into a puddle. Takes about 30 minutes of constant attention, watching the color of hot spot and adjusting O2 levels. Not for the faint of heart or those in a hurry. kcj Quote Link to comment Share on other sites More sharing options...
