Dougs D453 headers with TTI exhaust?

You have a "full" TTI system. You can pretty much put whatever kind of header you want, (except fenderwell). I have A body with TTi 3" X-pipe and cheap *** Dynomax headers , cheapest jet hot coated I could find. Put headers on first then figure out what pieces of manderel bent pipe it take to hook it up. Welded it together and it worked out fine. Wish I had saved my money and bought TTI. For a Mopar, nothing better than TTI, just my opinion.
I have TTI C5's on both my B-bodies along with their full exhaust and Ultra Flows with no complaints what so ever. Picked up a couple of 70 Dusters for a father/son project (I seem to be doing most the work lol) and was trying to save a few bucks. Probably should just go with the TTI's since both these brands seem to have the same z-bar issues.
