On our single tube side pipes the elbow can be adjusted 20%in all directions before the elbow is welded to the flange adapter. So you can put it on the car and draw a line around the elbow where it enters the flang, then take it all off, cut off the excess elbow and weld to the line. The big advantage is being Abel to change the glass pack in ten mentis the home shop guy can mark them and tack them to be welded. Bill E EMS
