Does it matter which end the cat converter gets put on? I dont see any flow arrows or anything of the like. Is it universal...Confused?

Are you sure...I think I want one or two more opinions on this, before I tear the whole think apart again.
I currently have the converter with O2 sensor and the front before the converter. Not after it. Is this a problem or not. I have no check engine light and no problem with performance...Although I thought I would notice more change witha header and high flow cat - 2.25 back........hmmmm....anyone else....NJHK...I bet he would know for sure!

The 2nd o2 sensor is designed to read the gases AFTER the cat and determine if the cat is still effective.
It compares readings w/ the first o2 sensor in the manifold- So yes, it SHOULD go behind the cat.. However, I don't think it would actually hurt anything to be in front, it would just make the sensor pointless.
im gona guess the sensor is after the cat so it reads if it filters the @!#$... makes more sence.

gotta love untrusting people
the o2 bung is on the exit side of the cat , or towards the rear
Agreed...thanks for the info....BUT one more question...do you think it is making a performance difference or not. I expected a little more OOMMPF after I made this change...or maybe its just me...
Thanks for all the help....

Sorry..............forgot one more thing........My cat is installed backwards!!!!!! -Is this a performance problem or not? Sorry for the double post.
Backpressure? The Cat looks the same from both ends!

it should cause any performance issues
just makes it hard for the o2 sensor , to read the cat unless that bung is caped off , and they used something else to read after the cat
it should
NOT cause any performance issues
sorry didnt catch my typo tell i hit summit
