    Anyone use this combination ? any install issues or did they line up well ? Seems Doug's vs. TTI are very similar; vs. performance, length, size, etc. Please correct me if I'm wrong. In theory they should line up well. but thought I'd ask the experts. (yes, you guys) :)

    for a 69 Charger , 440 , 727 trans.
    Dougs p/n D452
    TTI p/n XB25MP6670 (2.5") or XB30MP6670 (3.0")

    thanks in advance !

      I cant speak to the TTi x-over, but the headers fit the car great, mine are 2" and I only had to massage (slightly) one tube where it passed by the passenger torsion bar.

      The only thing I can tell you is I run 2" TTI headers and their 3" exh with an X-pipe out the rear of the car. And everything fit perfect. Good luck with yours as I do agree the Dougs headers and TTI's seem to look alot alike. Ron
