My header flanges are connected to the flat four tube flange that lesds to the to collector with eight bolts and another copper gaskets that I made myself. I went a different route on the collector back, I used Burn's 3 1/2" stainless V flanges and clamps. I had the flanges all tig welded to the collector mufflers and turn out elbows. Before I had the whole bunch ceramic coated. I can remove the mufflers to switch between three different sets of mufflers. I can add or remove a Car Chemistry disc units to the collectors and turn the elbow any direction or even connect elbows directly to my collectors.
