Pypes exhaust
Mine was a little tough to install. I did mine by myself, 2 1/2" in a 1968 Dart with Dynomax welded Ultraflow mufflers, started with the tailpipes and moved forward. After 3-4 hours of laying on my back and not a whole lot of progress to show for it I quit for the day. I had to spread the aft pipes on the "X" out a couple of inches. I used a floor jack to do that. I still had to fight with it a little but it ended up fitting.
I thought the part from the "X" forward would be the hardest due to havine Schumacher Headers, but that was the easiest part. I ordered Flowmasters 6 piece "S" bend set and only used the 4" offsets to mate up to the headers.
Overall I think it took about 8-9 hours over 2 days and I had to make about 10 cuts to the pipes (I even had to cut the l/h tailpipe tip, it stuck out about 2 " longer than the right side. I would recommend renting one of those chain pipe cutters from the parts store unless you have a band saw.
Somehow after I tightened everything down, the right muffler got tweaked, I still need to address that. Also I bought some universal tailpipe hangers to weld to the tailpipes so as not to see the ugly clamps hanging down.
