Caramanos2000 Posted March 17, 2009 Share Posted March 17, 2009 Took off my downpipes to replace the gaskets and I noticed that one of the inner sleeves on one side had broken off. So now it rattles at idle and im sure limits airflow.... Should I leave as is or have one fabd up? Link to comment Share on other sites More sharing options...

Caramanos2000 Posted March 17, 2009 Author Share Posted March 17, 2009 Negative ghost rider.... Let me explain it better: The downpipes up to the point were they meat is made of 2 metal tubes, a sleeve and the inner one which actually carries the gases. Well now one of the inner portions on one side snapped and I cant take it out because it bends... Meaning it simply sits inside and rattles, not much but it sounds like doo doo :-\ Cant imagine the gap is good for airflow The inside pipe is what broke, IE: have no exhaust leaks...

Quidam Posted March 17, 2009 Share Posted March 17, 2009 The inside pipe is what broke, IE: have no exhaust leaks... Hi, What you're seeing sounds like an "air-gap" front Y pipe. I'm not sure if that's the correct name but I had one on an '87 GL. This pipe has no heat shields and is a pipe, within a pipe. I ended up brazing the two together to stop the rattle after using a pipe expander on the inner one. You may want to just replace it. Doug Link to comment Share on other sites More sharing options...
