Cross posted from Other Marques, but I think i'll get a better answer in here..

I noticed when walking back from town that strands of what I could best describe as thick hair were trailing out of my lodger's ford fiesta. There seems to be too much of it to have been stuffed up there by someone.

I thought it might be the lagging from inside the exhaust but I dunno.

Any Ideas as to what it could be?

 

Had the same on a XR3i...the cats colapsed and it could block the exhaust all together....

 

Thats the inner part of the exhaust silencer system. Basically new exhaust is needed. If you pull it out, you could be there for a while !!!!!!
