    So i finally decided to get my head-work done woot woot! And I plan on posting vids of the awesome sound when its done. But before the guy can finish it he asked some question about my headers. I think it was whats size is the headers main port. if that sounds right. Anyways i am not really sure where to measure this or how to, so if someone can show me, give me a rundown, or find some numbers for me that would be great! Thanks in advance for the help

    Just take the header to the guy that is doing your head work. All he wants to do is match the ports in the header to the ports in the head for the best flow. Easiest just to let him do it, Plus then you know he didn't write the measurements down wrong, and you know its correct if he has the header.

    For the Best results make the drive, Otherwise, who knows how its going to turn out even if you do give him measurements. I would just drive there, but then again I drive an hour to work every day so I'm used to it

    Hoping i can get a mod to mark this resolved, not sure how to myself. Anyways, I should of just taken Redwidows advice from the start, but decided not to in interest of saving time.Turns out googling till my eyes bleed took even longer, but i finally found it and on eBay of all places...

    Anyways summit racing had an auction for my same model number and had the dimensions listed (i wouldn't of trusted it if it wasn't summit, always had good luck with dealing with there website)

    Collector Attachment Stock flange
    Collector Diameter 2.000 in.
    Flange Style Standard
    Flange Thickness (in) 1/4 in.
    Gaskets Included No
    Header Finish Ceramic coated
    Header Material Steel
    Header Style 4-2-1 two-piece
    Motor Mounts Included No
    Primary Tube Diameter (in) 1 5/8 in.
    Primary Tube Gauge 16-gauge

    There is the info if anyone else has the DC sports header model #MHC4001 and needs the numbers.

    On a side note, if you are ever searching for DC items, its much easier to Google the model # than anything else, i tried 420a dc header/ DC sports header/ dc header dimensions/ talon dc header, and about 100 other things. Model #'s are ones friend
