ok... my next mod is headers etc... im going w/ slp or mac mids a cut out then the cat after the cut out and a hooker cat back... my question is this... do i need anything else i here all this talk about O2 bungs or sims or what not and i really dont have a clue... is this only for 94+ cars? or is it all the same? help

 

I'm pretty sure you will need an O2 sensor before the cut-out in order for the car to run right with the cut-out open.

 

referring to the 02 simms i believe those are only on 95+ cars. I have LTs for my 94 and i didnt need them

 

o2 bung, is to add o2 sensors by the collectors if your headers didnt have the fittings for them already.
