EDL-67083 is what you would need, but on Summit it says that it doesnt fit the man. trans trucks. Im guessing that the 2.5" y-pipe that comes with them is a tad bit too big and would need a lot of massaging to work and really wouldnt be worth it. Your best bet would be to get a set of JBA's or Pacesetters for your year truck and then have a custom y-pipe bent up to fit better around your 5 speed. That is what im gonna do once i do my 5-speed swap.
