Removing Cat Converter

I'am in the process of having my cam upgraded and also the intake. Thinking about a set of tight tuck headers and dual exhaust. When I remove the cat converter is there any thing I have to plug off or disconnect?

Thanks for the info luckily I live in Eastern Washington where the govt doesn't control to much of your life, yet.

Flowtech have a nice fitting set of ceramic headers. The alum reusable gaskets seal really well.

Hooker also makes a pre bent fit dual exhaust less mufflers and tips but includes all the clamps and hangers.
