I have secured an OEM muffler that has part of the inlet cut off. I'll have to take it to a muffler shop to see if they can attach it to piping on my car. I'm not out of the woods until I know, but I'm suspending my search at the moment. Still, I would like to know the part number of the Camaro or Firebird muffler that everyone was using as a replacement. I think it was made by FlowMaster. Or maybe just tell me what year Camaro or Firebird it fit. Thanks.
