Not here to debate whether one should or should not remove the catalytic converters, its not something I would do.
I know someone with a 99 chevy truck, they dropped the cats and I know some vehicles you could add a little eliminator where the O2 sensor went. But I dont know if thats available for this model computer/truck?
Any options short of going into the ecu?
thanks
LSX conversions, so easy a caveman can do it.
i've been driving 3 weeks with catless LTs and ain't got any codes yet.
but then again, i also removed the EGR and ain't got a code yet, so i don't know what's going on there.
00 FRC - just top end, exhaust, and a hot-air intake

Once upon a time.....some companies carry excelent rear oxygen sensor emulators.
But the the ogre Federal Agency start hunting them and charging for breacking federal regulations.
Companies strike back by saying "off road only"
A few survive....not much !
Probably you can find something in ebay, but not reliable at all !
SHHHHHHH! Dude everyone on here has cats on there truck
