The rest of those brands are pretty much the same basic design that has been around for years
Even the Invidia race big tube header? That seems to be the closest in design to having a real merge between the two heads' primaries just like the KillerB. The other ones I fully agree are poorly designed, they just dump the one set of primaries at way too steep of an angle into the second set of primaries to be any good. The only one I could see being any competition to the KillerB is the Invidia big tube race, any expirience with that header? KillerB still seem superior in design to that? Thanks for your input.
