Another Ausie shipment? Make my life H*ll, why don'cha.
I sent some pipes down under a few months ago. In order to keep shipping costs down, I got a special set of pipes that had separate header and side pipes. Spent two hours packing them in the smallest box possible (shipping costs by volume at that weight) commensurate with low probability of shipping damage. The shipping was still almost as much as the parts.
Sorry. Not going through that again. Basically lost money on the whole process.
There's got to to someone down there who can do it. Or try Superformance.
