Thanks Ken,
Yes, I am sure the front/rear orientation of the carrier bar is correct.
At this point I am thinking that the thickness of the new rubber mounts
is what has caused the bar to be just close enough to the header pipe
that there is occasional contact ( only when the engine makes a jerk,
such as start and stop).
As far as the quality of the Dansk pipes goes, I can only say that I got
one header that had a cracked weld at the flange and a cast iron
collector piece that required that I grind the bolt heads down so they
would fit. I was not happy with the quality, though I understand that it
is still better than no aftermarket option to choose from.
