obx exhausts/headers?

this has the best pictures/description of them so far (even though it’s ebay)

now that i’ve looked at them a few times, they look knock offs of the flp headers and i’ve heard that some people cant get thier drain plug out of the pan once the flps are installed :ugh: . i’m probably gonna just go with coated pacesetters since i know they’ll fit and last.
