removing which cats will you have gas odor?

Ever since I replaced my fuel system with new fuel pumps and sending unit, the last thing I want is to smell gas in the car. I want headers which I know deletes the primary cats and the X-pipe which delete's the secondary cats, but I don't want gas odor, which setup should I do then?

I've got MBH longtube headers which require the removal of the 1st set of cats...

Never noticed a fuel smell with only the 2nd set in place.

I have no cats and have no gas smell. If I have to start my car in my garage (for yet another failed suicide attempt, or just to go for a drive), I just push the recirc button until I get outside.

Primary and secondary cat delete with no resonator and I get fumed when I run it hard, or sitting in stop and go traffic when it's 100*F+ outside. Regular/mild driving I have no fume issue.
