I have ebay knock off headers but the welding is good. There is no flex section in them, or do you mean the sliding expansion joint?
There are several different quality ebay knock offs. Do you know which ones you used?
The fabricator seems to think the quality and build is as good as GTSpec. Certainly has the same casting marks on the flanges, welds are all robot welds and they were hand ported before delivery.
The car is quite a way off starting yet so there won't be any sound clips for a while.
