i just got mine done,
i went anywhere on the midpipe, a place that was straight. the next thing is to make sure that it does not get twisted while it is being welded. I spend 35 for 1 cut, 2 welds, and a piece of pipe.
looks great and work magic! i measure something like 27inches from the hanger to the part of the pipe that start to move upwards. just line it up and keep that 2 in mark!
