1.75 inches

hmm, is that from the outside of a exhaust tube to the outside of the next exhaust tube? or is that the inner to a inner

my 4age measures, inner to inner 2 1/8", outer to outer 1.75 would work.

more more, i went up to discount auto today and they wouldn't let me even look at exhaust gaskets, they said they wouldn'y be able to sell them after i opened them.

outer to outer...dont go by the gasket...mine was spaced bigger than the actual ports

don't forget about the bolt pattern....

i have a stainless 4age flange already made, its just equal length honda manifolds are MUCH! cheaper than customn toyota ones, so i will buy a honda one of ebay for 200 bucks and weld it on too my flange,.

Just make sure you TIG weld... Stainless is finicky!!
