As you all likely know, the TMH lead time has gotten absurdly long and OBX headers only pop up once and a while. Since these headers are the only off-the-shelf options for replacing stock cast manifolds, I can certainly see where they have their place.
However, I've been wondering lately how bad it would be to make DIY headers with an online kit. There's a lot of SBF header kits out there, most with either 1 5/8" primaries to 3" collectors or 1 3/4"primaries to 3 1/2" collectors. The kits are pretty reasonable compared to TMH and OBX, coming in at $150-250 for collectors, bent tubing, and flanges (even gaskets and hardware in some kits).
So why aren't more people making their own headers? Do the normal "SBF" header flanges not work with GT40P heads? What can be done to make a new EGR tube to work with custom headers?
