    These are being released next week and a few vendors are taking orders, HHP has them 10% less than the others, there is a very short run of these ( 30 ) and 10 are spoken for .

    The 10% OD is a test run, when these were first ordered from ATI there was no tuning available, I would think 15%-17% will be next if these work out.

    Thinking about getting one of these...HHP should have an unlocked tuned ECU made for the 10% OD and another for pulley and headers supposedly... ARH has a new set 2" primary to 3" that should move a LOT of air...they have an entire exhaust with it but I don't see much need in changing the exhaust itself... the 10% OD should add between 2 and 3 lbs of boost. If they do a 15% or 17% later on that would pickup 3-5 lbs.
    I'd like to see a complete test car and what it picks up with pulley and headers plus tune first...but otherwise READY to go :)

    15-17 % will be a tight fit. I'm not changing exhaust. mine is tuned already and will make changes for new pulley. HHP sent me a t-state to see if it fits a hellcat and that will only help.

    One of the things we are trying to find out is the point where the factory headers max out and from the data posted here on a few builds I don't think long tubes were needed on those builds.
