70chevy03ss Posted July 27, 2008 Report Share Posted July 27, 2008 Ok I did a lot of searching on here and i got some more questions. Ok first I bought a set of Lt OBX headers for a member on here. (thanks Rick-Vor). I want to put them on but should I get them coated. I do live in mass. And I will be putting on a Procharger. 2: Will I pass Inspection with them on????? 3: should I or do I need to get a tune????? 4: can I or should I use all of the o2 sensor ports Please guys I need to get some more info on this.. thanks in advance.

kersey Posted July 27, 2008 Report Share Posted July 27, 2008 the only way to pass inspection is with CAT's on with all O2's. the factory cats will need moding for that header or you will need to purchase some aftermarket cats. If your getting the procharger soon i would wait and get the tune with it. get them coated!!! Quote Link to comment Share on other sites More sharing options...
ces63ss Posted July 28, 2008 Report Share Posted July 28, 2008 get it all done at once so you dont have to be retuning your pcm. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted July 28, 2008 Report Share Posted July 28, 2008 Jesse, since your in MA you definitely need to coat them, the harsh winter road salt will pit the crap out of bare stainless. You will need to re-tune for the new headers as well. Plan on having new mid-pipes with high flow cats fabbed up with sensor bungs so that you will pass the visual inspection. It is up to you if you want to wait and tune everything at once, or take it in steps. Does MA do an ODB read for inspection or do they use the sniffer?

It is NEVER going to happen. The EPA will not allow old cars that used to be emissions controlled to become non-controlled. The only thing that I could see becoming reality is the removal of the dyno from inspection stations. Less vehicles require its use, and they are very costly to rent and repair. This would mean emissions testing for 84-96 vehicles would be a two-speed idle with a sniffer (which is much easier to pass). And no matter what, you will never get away with straight pipes (legally). In order to pass a visual inspection, a car that came with converters must still have them on. Even though you might not have to pass emissions, you would still need cats to get a sticker. In either case, I'll believe it when it happens. Right now, it's just a rumor.
