You can buy flanges, and yes mandrel pre-bent pipe is available. I have never built a header, but I am sure it is like anything else new. The first one takes forever, and the second one the time is cut in half. The third even less than that.

I think I went to Hooker Headers, and found flanges. Some with a stub already welded on, and some just the bare flange. When this new shop can finally justify buying a kit. I am undecided if I will go the easy route, and purchase the header built for the kit, or make my own. It was not cheap to purchase the parts to build a header. You will save some money, but the time doing trial and error may not be justified?

I have installed many of the electronic gates that by-pass the muffler. Also there was a muffler that had a straight through side, and a baffled side with the electronic gate. I don't know the cost, because customers bring them into me for installation.
