A couple of weeks ago I installed the OBX header in my 2010 focus, and I already had the Magnaflow HFC and FWERKS Street exhaust installed. I also had a tune before the install and have a tune but WOT isn't finished with the new header. I been busy and haven't gotten a chance to finish it. It seems like the past couple of days my exhaust has started to make weird noises, mainly coming from the exhaust tip. It sounds kinda like a rattle, or something I cant really explain. It may also sound like its coming from the engine and carrying out through the exhaust. I took a vid of the sound, it's a little harder to hear on the vid versus in person.
I'm going to check my bolts on the exhaust and header to make sure it is all tight still, maybe gotten a little loose and causing it to make this noise?
