Not an M3W owner and not knowledgable about them but...... Are the exhausts bought in or made in- house? The RH one looks to be a different curve to the LH one when they should be symmetrical? I assume a jig is used to weld them up? Is the pipe bending done in a CNC type bender or by hand and eye? Cracking.....either poor welding/ wrong filler metal or vibratory stresses or both. Good quality management should prevent these things happening by proper design of the parts themselves well before actual production and their manufacturing process designed to prevent poor parts and then subsequently monitored by a sampling regime properly set up. If an outside supplier is used then are they tackled about parts out of spec( assuming a correct spec/ tolerance has initially been set). If in- house the internal issues need to be tackled. Maybe the on- going issues could have been avoided? Rushing through the design/ spec stage can lead to costly future problems both £££ and customer confidence. The M3W is a real showstopper for Morgan but sadly seems to have been plagued by design/ quality issues. I now wait for the backlash!
