I really really need someones help. I bought headers for a civic dx off ebay. They came with the headers and the downpipe. On the downpipe was a hole for a second oxygen sensor, but there was also a cap that screwed into the hole in case you dont want a sensor there. My problem is that i didnt tighten this cap and ti came off at some point and i have a stupid exhaust leak. there was also a similar cap on the oxygen sensor hole in the headers. If anyone has this cap and can send me one, PLEASE let me know.
