Replacing a catalytic converter no arrows which is in and out - which way to mount?
 

I am going to replace the exhaust from the cat back including the direct fit Walker catalytic converter model #15538 on my 1993 Toyota Camry 2.2L 4 cylinder. The converter has no marks, arrows or anything showing the direction the converter should be mounted. Both ends of the converter are exactly the same in diameter and could be mounted either way. Anyone have any ideas?

Is the catalytic converter for Camry 2.2L 4 cyl a two stage cat or a three stage cat??? it kinda pisses me of that the catalytic converter for this model has no marks at all.. It would not be hard to put one there right..

Test fit the CAT in both directions, one direction may fit up better then the other to the attaching pipes.

Otherwise the CAT is a straight through design, inlet and outlet makes no differance.
