ok, i have taken off both manifolds and the pump looking thing for the A.I.R. to the right of my opti. Now my question is how do i get that metal tube that went from the right manifold to the left manifold out



also after i get the rear egr parts off the intake manifold what else is there?

i noticed a tube going from the left valve cover to the TB, does that come off as well, If im not mistaken i think that is part of the AIR system

Thanks guys,
Scott

I took a hack saw (a dremel would work better) and cut the metal tube in three different places to get it out.
This should help you too

this was one way i thought of getting it out, but dont have my dremel at this house. its at my other house ................however i think ill go buy one for this one.

THanks, this is probably thie easiest and quickest way

It doesn't take too long to get through, the pipe is thin metal.

No.... do NOT remove that tube. It supplies air to the PCV system, that has been filtered and measured by the MAF.

You will probably get codes and SES light for the removal of the EGR and AIR systems. They either need to be programmed out of the PCM (leaving you with "system not ready" warnings - in the event you have emissions testing, where they hook up to the ALDL connector), or incorporate a circuit that places a resistor in the MAP sensor circuit when the EGR solenoid is supposed to activate.

There is really nothing to be gained by removing these systems, other then eliminating a little bit of plumbing for the AIR and a few #'s of weight.

i have a tune in the mail...............

and no emissions in my state..............

just trying to free up clutter in the engine bay, If it doesnt work.......y have it in there?? IMO

But, EGR does work, helping to reduce combustion chamber temperatures under certain engine operating conditions. That, in turn, reduces the possibility of detonation (knock). You can also think of it as a mini "displacement on demand" system, reducing the air and fuel consumption of the engine under "cruise" type conditions.....

Remove it if it makes you feel better.

i also would recommend keeping the EGR system, no point in removing it whatsoever.

already bought the NON-egr ready headers

ah... no egr it is

And don't forget that if you have an LT4 hotcam or something with similar overlap, the EGR is redundant and not needed, hence the reason LT4 motors have no EGR.

cool, I think i will just be getting an EGT gauge and put it in the collector of the y-pipe (where it goes to the cat-back). That way i can monitor temp and that way i know if it gets to hot.

Thanks guys.
