Those big divits in the cross member ARE for exhaust. These days there are all kinds of exhaust parts including "oval" bent fittings. Don't know what else to offer. Buy bends/ cut/ weld?
I understand what your saying, but the header exits about 1 foot or so from the cross member, there is no way to reach the divit with a conventional system. The ovals may work if I can find some. Will be working on this for a while.
