This is a used BMW E34 M5 exhaust header. It is from an S38B38 version of the M5 but should have no issue fitting S38B36 versions as well. It is in good condition. Additional parts included as shown. This is not tested but visually appears to have no material damage or defect. It has the usual grime and light rust in certain areas. The only area with any moderate rust is past the collector where it is mated to the rest of the exhaust system. I would recommend giving it some love with a rust remover and a high temp coating. The air injection system is intact as are the testing points.

This was intended to go into a project car of mine but instead sat neatly in a storage container for about a decade. As these are becoming more difficult to find, I am putting this one back out there so it can go to good use.
