    Are those factory heat protections pads protecting the chassis? Looks brand new, which is why I'm asking. Those headers look awesome (the whole exhaust system looks awesome), and that is some nice power you're making with that setup. Are you going back to the dyno with the headers?

    Hopefully they will do a pull & check vitals after header install? Beautiful pipes. You're going to love the sound + the extra power ! Are you running 373's?

    Do you need boostane with those mods? im very similar to you and doing headers in springtime but didn't plan on needing boostane...

    Only use OEM header gaskets, Van is right. Trust me.
    Once all your mods are done, and you start tuning, read your datalogs. If you're getting a little positive knock than add some boostane. Every engine responds a little different.

    Picked it up and it sounds wonderful!
    He did tweak the tune,I told my tuner I wanted it stay on the conservative side. Pulled 741/739.
    Still running 3.31 gears.

    Nice ! What were your numbers before the headers? Are they a lot louder than before ? Its the one mod I'm thinking about doing soon.

    733 before headers and yes it's a noticeable difference in volume!

    Update....the combo I have with LTH headers and X pipe with the Ford Racing mufflers is ear shattering loud if you are behind it when you rev it....3000+
    Up to 2500 rpm you are okay inside...then things start to get loud.
    YMMV.
