Of Cats and O2 Sensors (1 Viewer)

[gnarlytoes]

It's time to work on the WarPig's exhaust. The noise and leaks are getting annoying. She is a '92. I'm ordering new cats and O2 sensors. O'Reilly, Autozone, & Advance show different parts for right and left O2 sensors. The right sensor costs twice as much as the left. Does this make any sense? What is the difference?

I need to redue my downpipes catalytic converters also, this past Cruise Moab twisted things a little. Its been about 4 or 5 years sense the cats and O2 where repalaced.
Looking at Catco brand they say they are stainless, Summit racing has them priced competitively and can only be better then the other brand I currently have. O2 sensors I probably pull from Rock Auto and the only difference from left and right is the wire length.
