Does anyone know where to get the muffler for a 91ac, or actually all I need is the conical end piece. My cowl is already cut out for this muffler, but if I cannot find does the 91fz muffler fit or what are my other options?

A replacement is available from Performance Specialties. Call them at 775-265-7523 weekdays from 9 to 5 west coast time.

Thank You
