big problem.


I would take the flange off the motor and make a new one that is a tighter fit on the exhaust pipe.

or heck. try and bolt it back on, it might hold. Mabie weld a bead around the head pipe.

a picture would help out alot.

my buddy just had this happen to his FMF pipe also. It appears the flange is just pressed onto the end of the pipe and eventually comes lose allowing the pipe to come off the flange. He just had the flange welded back to the pipe and problem solved.
