i dont know how, but some how the connection at my h pipe to header came loose, and the top bolt was able to unscrew it self all the way while i was driving. so now i have a super leaky exhaust, and I have no idea what the bolt size is. can anyone tell me? if you dont know, can someone atleast tell me if its metric or standard so i can eliminate some guessing? they are factory parts so whatever ford used is on there.
