The EGR will not cause this issue, this sounds like the Catalytic Converter was not hot enough, another trick that worked for this kind of fail was a fresh oil change, make sure the engine is up to normal operating temp, which would be just short of 1/2 scale on the temp guage, if it runs cold replace the thermostat, I did smog tests for 30 years and these are the things I did to get cars like yours to pass given the test results you gave for the tailpipe.

well,if you know how to install the egr valve,i recommend doing it youself because the part is NOT covered under dealer warranty.i have an 05 300 limited and had this work done.the total cost will be between $480 - $600 dollars at the dealership.if you know a competent mechanic,take it there instead.the part cost around $200 dollars.

The trick to setting all the monitors is:
Make sure you have more than 1/4 tank of fuel but no more than 3/4.
Clear codes then Do Not cycle key off. Start vehicle and drive,make sure you do at least 2 minutes of steady spead between 40-50 mph and at least 2 minutes at 50-65 mph, usually about a 20 to 25 mile drive will set them..
If you turn the ignition off before the monitors complete then EVAP will have to see a 6 hour cold soak before it will attempt to run again.

P0401 shows an Exhaust Gas Recirculation Flow Insufficient. Without a good scan-tool you will be playing the "Parts Changing Game". Insufficient flow can be the result of a vacuum leak, bad MAP sensor, an exhaust leak, faulty EBP sensor, carbon build-up, and so on. I wish I could say more but with all the electronics it is more complicated then earlier cars.

Most likely evap vent solenoid needs to be replaced. Locate replacement solenoid at auto parts store or dealer & replace.
