Assuming your EFE is vacuum controlled, as an interim, just disconnect as much as you can from the flapper valve, make sure it is in the open position, and don't worry about it. An open flapper will have little effect on a stock exhaust system. If you have a welder, tack weld it open just to make sure it doesn't close.

For the AIR system, leave a bit of the tubing and just crimp is shut on the exhaust manifold ports.

If you are planning on sticking with stock type manifolds, just look for a set of pre emission ones without the AIR holes. Usually a few available for little money from folks installing headers.
