"This bike is so hot that it's pipes turned blue"
I'm in the camp that doesn't mind the blue, or the gold of heated up SS pipes.
The worst pipes I've purchased to date were a Siamesed set for the BSA. These came from Armours. The left header angle was off by a good 15 degrees . The sharp left header bend included a series of very visible creases about 2 " apart.
I have also purchased items from Armours that were very good.
