    I have them.
    I used TA conversion frame and motor mounts.
    Tubes 1 and 3 hit the frame.
    I did some singing in bottom and at bend to fit.
    Called them. They said I should have just sent them back.
    I said how would you know what to change.
    Regardless. Good fit now.
    You must use remflex gaskets.
    Mine are in coated. From 2013 I think.

    What hype?

    I highly recommend them.
    But they may take some extra labor.

    That they are a PAIN in the ass. And why would you do that to your car. That’s all i heard. when switching over. And removing the Original exhaust. I mean. Damn. It’s bolt on accessory. Can always go back down the road. But i’m wondering why i did not have to cut my wheelhouse . And thank God for that. that the headers fit.

    I've never had to cut fender wells when installing M/T headers.

    You always had to cut them when installing those Hooker Super Competition headers, the primary tubes from cylinder #7 and #8 went straight out thru the fender well and wrapped around the frame to join back up with the collector.

    Talk about a pain!!!

    You can't download video files to V8, you have to download it to Youtube, and then link it. Can you do that? If not, send the clip to my e mail (in my signature), and I'll do it.
