what sup i had 2 take my secondary 02 sensor (the lower of corse) the one that was in my car when i put in my new exhaust (apexi ws2) but this got rid of my cat, in all there is no hole for my o2 sensor... so im wondering is there any dummy sensors i can get... or is there a way without drillin it in i can get rid of the check engine

 

you can buy an o2 sim. costs around 50-60 bux i believe

 

any ideas where i can get that...

 

if you can make this (or know someone that can) it works great...

without that o2 sensor your car is gonna run rich and your fuel economy is gonna go down. Any respectable muffler shop could weld in a bung

 

so do you think i could take my old 02 sensor sauder it back on n take my car 2 a shop and ask them 2 get it in... would that work?
