i used them and had to cut the collector on the driver side to angle it into the center more, had to trim the frame rail on the pass side about 1/2 inch for the length of the collector to keep it from rubbing. they do work but not just a bolt on deal. i used long tube headers, i realized you are talking about the stock manifolds, sorry
