    I recently bought a set of SLP headers used, but they didn't come with the end that has the rear O2 bung, catback flange, and exhaust hangers. What can be done as far as replacing it? I can't really complain too much, I got them cheap and that's all they're missing

    you need a step tube, from 3 to 2.25 and a flange on the end to the res. a shop can weld a bar on for the hangers.

    Would that be the right length to go from the headers to the exhaust?

    the one that comes with sd headers is like 4 inches long maybe. not sure on the slp's.

    you could always ask them to make it longer and trim i back. tell them you want to put a 3 inch pipe inside it, or just bring the dp with you. no mistakes that way.

    good idea to get the rear o2 bung welded in too. being your a 04 and need the o2.

    If I remember right, the SDs are supposed to be pretty much copies of the SLPs, so they should be the same, but I'm not sure. I'd just like to grab the u bend delete if it'd fit, that'd be a lot easier

    I have SLP Headers.

    These headers don't really come with a downpipe. After I installed mine, I brought it to an exhaust shop and have them weld on a 3 inch pipe where the downpipe would be.

    It's just a 24in long (estimate), 3in diameter tube. Cost me like $50 for the pipe and labor.

    install the headers and take it to a shop, have them seld the cat to the pipe there off the rear header, then a add a new pipe off the other side to the cat back with a reducer.
