    Yea, they have quite a few for duals, but none of them have the SE slip-ons listed. It's just a matter of figuring out which slip-on has the closest characteristics (flow and size) to the SE IIs. Think I'll call their tech support and get it straight from them. Will report their response here...

    5 minutes later:
    Well that was a quick call. Here's their suggestions to start with:
    M807-034 True Dual headers, Vance & Hines Basic slash cut slip-ons, Stage 1 ECM and Screamin Eagle air filter
    M807-050 True Dual headers, Bassani slip-ons (long core), Stage 1 ECM and Screamin Eagle air filter

    I was wondering if the White Bros E series slip-ons with 10 or 12 disk would be a bit more restrictive like the SEIIs

    With only 10 or 12 they might be closer as long as they do not have the end cap with the center hole.

    Map M807-048 does say 12 disk with closed end cap.

    Map M807-186 just says 10 disk.

    I think I'll try the 186 first and see what I get for performance.

    I've compared the other two they suggested and there are enough major differences to see they flow a lot differently.

    It would be easier to Dyno tune it and be done, but I just know there will be some other engine changes in the next few months, so I would rather save the money for dyno tuning until I'm satisified with everything.

    Thank for all the help
