I have acquired Rinehart mufflers for my 08 Road King. The problem is that the inlet is 2", while my headers are 1 3/4". Does anyone know of an adaptor that's been proven effective to attach these two together? From what I can figure I need to add something like two 1/8" half moons to give the clamp something to grab onto. I know bigger headers would be the way to go, but I'm trying to work with what I have. Any ideas?
