I have a 2010 sho with almost 200, 000 miles. For tbe past couple of years I keep getting the Po430 code along with a po455. One is a cat code the other is a vacuum leak. My exhaust shop can't find a cat for it or he really didn't try and when I clean the gas flap real good the code goes away until I get gas again. Anyone have any answers?

Plenty of aftermarket cats available. If the OEM cat is discontinued that's what you are stuck with. Unless you need a C.A.R.B. compliant cat, which is more difficult to find and much more expensive. Check Rock Auto.
A smoke test should find the leak. You may need to replace the filler neck.
