where did you read bad reviews about OBX headers? they just came out on market.
OBX headers give same power gain as Comptech ones, they look exactly like as Comptech, but cost only half what Comptech cost, so some ppl think Comptech will file law suit against OBX for coping their design.
OBX headers aren't CARB certified, like Comptech ones.
other company that will produce headers for AV6 is Prototype. they headers are equal length headers so they give much greater gain in middle of RPM but lose some in top end.
if want more info you might want to go and check this places;
