I have a Dearborn 01/72 Mach 1, 351-2V Mark (aka svo2scj) provided a picture of the single exhaust system he received from another party. The picture is not at an angle where I can see if there is a clamp at the intermediate pipe to muffler and muffler to tailpipe. I have an OE muffler I recently acquired cut off of a car in 72 and put away in the shed. It is in very good condition but it was cut with a saws all very close to the center chamber so it will need some new extensions welded on. I am trying to find out if the OE system was welded from the intermediate back?
