AIR System Delete Questions
I hope this is the right section...
I'm running a 1988 Camaro with the 305 TBI. I was reading around and saw that I could remove the AIR system from my car. The previous owner removed the catalytic converter and replaced it with a straight pipe. I live in Iowa and there's no emissions testing. I just have a few questions:
1) Since there's no catalytic converter, the AIR system is useless as it stands, correct?
2) To remove the AIR system, I just remove the pump and basically everything that attaches to it (The pipes, diverter box, ect.)?
3) Do I just throw some bolts into the now empty holes in the exhaust manifold?
4) Will this eliminate the popping noise my exhaust makes under heavy de-acceleration?
5) Is part number 10186167 the correct delete pulley for the smog pump?
Thanks in advance for the help.

Re: AIR System Delete Questions
I've never heard of anyone having problems. I ran mine like that for 4 years. A longer belt is used, but it gets wrapped in a different manner, so there is no long span without touching a pulley somewhere.

Re: AIR System Delete Questions
1) IMO that is correct
2) Yes, I was also able to remove the wiring associated with the system as well. I just cut it back into the harness and taped the ends. Been troublefree for 5k miles with no codes.
3) The exhaust manifold holes are straight thread. The correct part number for the manifold plugs is Edelman number 120500. Should be available at most GOOD auto parts stores.
4) Unsure
5) Yes that is the right number. I also felt it was a good idea to install rather than changing the belt routing or belt length. IMO the General installed them on the export cars for a reason.

Re: AIR System Delete Questions
I believe these are the plugs you are searching for if you want to get them online.

they are super cheap. I ordered 2 for a dollar and some change.

Re: AIR System Delete Questions
The plugs for the exhaust manifold tubes are NPT threads - standard plumbing stuff available at any Home Depot. Just take the check valves off and put the NPT plugs on.

Re: AIR System Delete Questions
Not sure I understand the question.
If your headers have the AIR tubes, then you plug them, if they don't, then you just delete the AIR pump and be done.

Re: AIR System Delete Questions
Awesome. I bought the plugs today and will plug it tomorrow. Do I need some sort of block plate when I remove the system?

Re: AIR System Delete Questions
Nothing to block except those little AIR tubes, and the line coming from the cat converter. On my cat converter I just cut the tube at the cat, pinched it closed with pliers, and welded a bead in the pinched hole with a torch and coat hanger.
