1964 Valiant "Get Runnin & Drivin"

My buddy @vitamindart hooked me up on a great deal on some slant 6 headers. He even blasted um for me so all I had to do was degrease um, prime um, paint um and clear um. I used VHT Flame Proof primer, paint and clear. I used cast iron grey, since I already had it and was no extra money out. I think they turned out pretty good for an old redneck and a spray can.

Once again it's time to parade my ignorance. First of all, do you know who made them? And, I don't see the usual triangle ring that lets you bolt the header to the downpipe. How do these connect to the rest of the exhaust?
