Put new stickers on the cans...you'll feel better.

A few of us who had the DP (Termi) shotgun CF slip-ons on our desmoquattro S4Rs, reported that the S-pipes were crooked as received. The only real way to fix them was to cut, rotate and weld.
I've since heard a number of stories centered around poor build quality for Termis, and I don't think I've heard nearly as many stories about poor quality for other manufacturers.
