Yes I did it, 9 inches, re-check it several times now, as far I can see the problem is a rotational malaligment of the tube, I think that this tube is for the right side, not left side, it has the same shape, just the hanger is different.
I installed it yesterday and I had problems with the left tube, not the muffler. It contacts the sway bar, I tried to adjust It and its impossible.
Anyone else with this problem? :shrug:
