Bought a used header for $40, Was told it was a procircuit but the problem with this header is that it has no stampings or plates welded on to identify the product or even have any welding marks of a plate removed. Very disappointed because it actually matches up with the dg header. What are the reviews for this brand? I heard it's a really bad brand to purchase since it's just a mock stock pipe. Also are they suppose to have some kind of baffle in it? I can put a tiny rock into it and the rock will fall out through the other end easily. Thanks guys
