I'm in the process of removing the exhaust from my S13. The previous owner replaced the stock exhaust with some no name headers and a straight pipe. (Middle of Nebraska, what do you expect?) I have all the header bolts removed, and I have all but one of the rubber bushings removed from the rear. I have two spots that I can't figure out though. One spot is a solid metal s-shaped hose, and the other is a slightly bigger, L-shaped hose that looks screwed into the header. I need this out fairly soon so I can put my new motor in. Any advice would be greatly appreciated.
