Car is misfiring on all but one cylinder but before this problem occurred we noticed what appears to be hair stuffed up the tailpipe ever since then the car has had problems with acceleration. Any ideas on where to began to fix this problem?

 

Sounds like the muffler is coming apart and needs to be replaced.

 

Could be a plugged catalytic converter. I don't know about the hair. Got a picture?

 

The hair has since been removed but I'm not sure if any sucked up further into the exhaust but something is definitely wrong
