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?

do you have any pics ? is it the inside pipe or just the outer shroud

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...

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.

Or just run a self tapping screw through it.
