Alright as the title states I'm trying to figure out whether or not to keep my egr and air systems. The reason I ask is cause I'm leaning towards buying some kooks headers and trying to decide which ones i should buy.EMISSIONS IS NOT A CONCERN. I've done some reading and I'll be deleting my cats anyway so keeping the AIR system kinda seems pointless. The EGR system however helps prevent detenation and I don't mind that idea.

 

If you are going to be removing the cats, then I don't see any reason to keep the air system. With the Kooks longtubes, I don't know if you would get enough backpressure for the EGR system to work even if it is hooked up. I would probably delete it especially if you intend on putting in a cam.

 

i guess i never thought of it that way (newb) the egr system would need a certain amount of backpressure to funtion huh (once again my ignorance exposed)

and the cam part is down the road but U have a point there as well

 

The EGR is not noticable, the AIR system however is. If emissions aren't a major concern and you are mainly just looking to clean a little bit of stuff out of the engine bay, then I guess it wouldn't be a bad route to go.

 

i was just thinking about the header install honestly. i don't have to worry about emissions and i figured why not get rid of the emissions stuff and make the headers easier to put in

 

The emissions equipment won't really complicate the header install.

 

Mine works just fine. The EGR system has nothing to do with backpressure, it works on vacuum from the intake.

If you don't have to worry about emissions, it's really up to you. You can have both EGR and AIR tuned out. If you decide to keep EGR, I would still definitely get rid of the AIR system. It would clean up a lot of room in the engine bay. Then you can just cap off the AIR tubes in the headers.

 

I had EGR issues after installing my long tubes and ORY but I was able to have it tweaked through PCM tuning.

 

That motive force is the difference between the pressure in the exhaust system, and the vacuum in the intake manifold. The larger the difference, the greater the flow. If you have low backpressure in the exhaust system, EGR flow is reduced, and the change in MAP when the system is operated is inadequate to meet the PCM's diagnostic routine, and you get a code for inadequate flow.

 

so what i'm gathering is i with long tube headers and no cats it really wouldn't be worth keeping either system ?

 

I would definetly get rid of the AIR system. EGR is your call. It sounds like to me EGR won't function 100 percent correctly with a opened up exhaust. So unless you were putting down some numbers that made the exhaust a bigger restriction again, it wouldn't be worth keeping. Good choice on Kooks, they have a reputation as being the easiest to install.

 

I agree. Excellent quality and fitment. Very good clearance on all sides. And when they turn gold from the heat...

 

Well . . .
Now that everyone has congratualted me on my kooks choice
I just got done sending Carl an email asking if he has any LT1 headers left.

But, depending on how that goes I may still go with kooks

But yeah I'm going to delete my AIR and Egr system, the air is a no brainer and the Egr sounds like it's more trouble to save it then it is to just get rid of it
Thanks All for the input and help

As soon as I get some headers I'll be posting a thread asking for help I'm sure

 

Im deleteing my AIR and EGR for the simple fact of not needing them, and cleaning up the engine bay. Also you may look into the "race" version headers if kooks has them, they do not have the bung for the AIR or EGR.
