Maryland Cats question

I heard that if I remove my headers and go with LTs with the HF cats I will have issues when its time for my emissions test. I live in Maryland can anyone tell me if thats true?

I've passed Maryland Emissions with a High-Flow Cat on a Turbocharged 4 cylinder (on a system that originally came with 3, yes 3, cats!).

They do a visual and then run a OBDII Port Check. If they see a cat and there's no CELs, then you're good I believe.
