Hey guys I am in the process of removing my exhaust from the manifold all the way back and starting fresh. I decided to do this after my exhaust started rattling and then all of a sudden just quit flowing.

I plan on making this a progressive thread as I go along I will have several questions I'm sure.

I bought a set of Hedman Shorty Headers that my girlfriend volunteered to model in front of the '82. ( )



After I install those, I'm going to have a full exhaust fab'd from a local shop. (but i can't decide. Magnaflow or Flomaster Mufflers)

Here is my tired TPI:

Passenger side :

Drivers side :


For my first question:

I've read a hundred articles about the AIR system on websites, but never seen removal instructions nor seen pictures of what all can be removed. After the painful process of taking off my manifolds, I have the AIR system sitting in my garage and the wires that run from it.






What can I get rid of? what do I need to eliminate? What do I have to put back on?

Im guessing you didnt read this.... https://www.thirdgen.org/serpentine
I did it on my L03 and it worked great. I clipped the wires and got rid of everything. Never had the SES light come on because of it either

Yeah, I read it but it didn't answer all my questions. I wasn't sure if I could pitch the device that the wires plug in to. And how far back did you cut the wires? And did you just tape them up and let them sit?

89rs305-DP

Yup, the device that the wires go into, the pump, and the tube going back to the cat can all go in the garbage. I clipped the wires back as far as i could, just so theyre out of the way, and then i used shrink tubing and taped them

You could always do what the P/O of my Z28 did.... Just left 'em hanging and eventually they fell onto the exhaust and melted.... LOL...

Did you see the sticky thread at the top "Can I remove my AIR system?"

Also, keep in mind the AIR system is an emissions device, and is required by federal law to be in place and functioning on all street-driven vehicles in the United States, regardless of whether or not your state or city does emissions testing.

Kevin91Z is correct in theory about the inspection issue.
In reality, you'll have to solve it in the context of your local
inspections procedures. And since these vehicles are older than
most of the yae-hoo's inspecting them (at least here in TX.),
visual inspections are the easiest to circumvent.

That being said, everything (pump, control relays, plumbing -- into the
old manifolds, and probably the CAT) can be removed. As far as
the wires, remember that each pair carries a 5 volt signal from the ECM.
So at minimum the signal wire should never inadvertantly contact ground.

My about where I'm going from the same point as you:
-- Headers have been ceramic coated AND wrapped.
(I want under-hood heat to be as minimal as possible.)
-- 3" Y-pipe into a 3" high flow CAT
(Removable, no AIR inlet. Since a CAT visual is more likely here, I'll have
a straight pipe section in 364 days/yr. )
-- 3" CAT back Magnaflow Stainless tailpipe, muffler, and exhaust pipe.

I did. But again, it didn't answer all my questions.

And with federal emissions blah blah blah. I don't need to worry about that here.

A small note when you remove all of the air components... don't just chuck them in the trash as the diverter valve alone is a $250+ part!

Sensor got a little hot at some point, eh? I took it out but probably just gonna screw it back in, see if it works ok. >.<

The hard plastic line that goes from the throttle body to this charcoal canister was brittle and it broke when i tried taking it off.


O'reilly said they dont carry them any more so my idea was just some rubber line. Any other suggestions?

Rubber line should work fine. Its what I did to extend mine to move my canister.

Sweet! Do you remember what size it was you used?
