Hello all. lm working on a 88 GT that l am putting back to stock. l took off the FM shorties and have a set of stock 94 GT headers. Now the question is, other than the little smog riser tube welded into one of the primary tubes, will these headers fit otherwise with factory h-pipe and everything else? lf so l will just cut off the riser tube and weld a plate over it. Thanks everybody!
