Whaddup guys!? So it's time to replace the front cats on my 03 xe.. I was wondering if buying oem cats are they way to go, or if getting some performance or aftermarket ones are simply better? The price is more or less the same and I am wanting to have a local exhaust shop do me a custom cat back exhaust system with removing the 2 rear cats and new muffler. Does anyone have some experience w this?
Also, AC has headers that I could smack on there too but says off road use only. That meaning it won't pass S/E for road use? Says they have o2 sensor spots but just wondering what the options are and the best bang for the buck.
Thanks guys

You will need the back 2 cats to keep the check engine light off

How does that work? Aren't there just the 2 o2 sensors on front 2 manifold cats?

4 cats 2 each side 4 o2 sensors 2 each side.

OBD2=2 sensors per bank, OBD1=1 sensor per bank...does not refer to how many cats you need
