If you will have a DC header / no cat between the first and second O2 sensor you will need an O2 sim, or will end up with a cel. And it's not a "maybe" it's a given.Originally posted by jito72@Jan 3 2005, 10:43 PM
Nope, No O2 sim is need. I already checked.
I might be wrong, but wasn't there a post about DC withdrawing the headers for a while because of that problem?Originally posted by basilisk4@Jan 5 2005, 04:24 AM
This has been reported repeatedly on other boards by people who have bought the DC Header.
