notslow Posted April 28, 2005 Report Share Posted April 28, 2005 I've just taken the exhaust system off of the 99 Techno for a clean. There was oil running from the end can/muffler. I've cleaned the end muffler right out and repacked it with the correct packing. It was filthy and thick with oil. I've also cleaned out the front pipe as best as i can with caustic soda, it's got some oil out but not all, but should be ok i reckon. I also put the middle section in the Caustic soda for a while, it started to fizz on the outside of the section and get hot. I've read on here that caustic soda eats away at alluminium, so i guess thats whats happening. I took it out and it seems ok. What i want to know is this. What is actualy in this section? Is there a packaging fibre in there surrounding the perforated centre? If so how do i get it out and if i can't will the packaging dry out enough so that i can still use this section? It's standing up in a bucket at the moment and theres oil slowly running out of it. Also theres a bolt on the top, what is that for?

terry Posted April 28, 2005 Report Share Posted April 28, 2005 Can't say for sure whats in it but I have done the same thing on my '01. All you can do to repack the mid-muffler is cut it in half then weld it back together or buy a new one for $350. I just left mine standing on end for 4-5 days, sprayed it down with solvent to clean it up and put it back on. I did replace the o-rings while I had everything down. Just hope whatever you poured down in it isn't flamable. Quote Link to comment Share on other sites More sharing options...
