Huh. Thanks for taking the time to document this info for me!
That means that there are two (2) different versions of the non-cat 3-into-1 manifolds like you have out there, both visually the same design. But one version with roughly 65 mm c/c distances between the outlet flange studs, and another version with this dimension as 75 mm as yours are.
The factory's justification for changing this c/c bolting distance at some point in the model run remains an odd mystery!
In any case, apologies for the thread detour, and we now return back to our regularly scheduled program.
Thanks - DM
