ok this is the deal.
1989 cavalier 2 dr 4cyl
the muffler kept coming loose and making noises so i took it to meineke
the guy looked at it and told me that i needed my bracket/hanger replaced
(i'm not white though)
so i asked him how much he said $65....

<------ i gave him one of these and said i'll shop around
so i hit up advance auto parts
got the bracket for $8.40 plus tax....
and replaced it myself today.
i noticed that while the muffler was loose, the heat of the pipe burned up a cord
WHAT IS THAT CORD AND WHAT DOES IT DO AND WHAT SHOULD I DO?
