Deleting your catalytic converter WILL cause a CEL as it will make your oxygen sensor readings messed up, which will then cause your performance to be poorer and give you horrible fuel economy. They are crucial integral components for telling how much fuel gets fed to your engine.

The purpose of your first oxygen sensor is to tell the computer how much unburned fuel is coming out the exhaust... the second one tells how the converter is performing, both of which will effectively control your air/fuel ratio and advance or retard spark timing accordingly. Without the converters or oxygen sensors, it basically detunes your engine into a gas-sucking pig that runs like crap and drives even worse. Oh, that and a nice yellow warning light shining in your face while you drive it.


I'll totally buy this for a $1. ^knows his stuff. Total consensus please don't do it.
