i have a "primary o2 sensor" short. I need to replace my o2 sensor and they are pretty expensive and i was wondering if there was anything like a bypass or eliminator(like MIL eliminators for my mustang).
thanks

you don't need to bypass the second one.

you'll just get a CEL but it has no effect on your ECU kicking into limp mode or anything like that...it's a warning.

I wouldn't just run without a cat. You need a length of tubing after the open header or a diffuser to maintain the exhaust gas speed or else the temp difference just dies and so does the gas speed...that basically kills your scavenging effect.
