Do I need to remap?
Hi, I'm looking at putting a 4-2-1 manifold and a full stainless straight through which has a decat, do I need to remap my car after this or will it be fine to run?

You'll just need to reset your ECU. Remove the neg battery terminal for 5-10 minutes, then replace, and the ECU will re-learn the fuel trims to level off your idle (about 5-10 minutes as well). It may take up to a day or two to really level off as it finishes the fine tuning.

Do I need the engine started when I remove the negative terminal, is this the only thing I will need to do?

No, engine off, remove neg terminal, install header, replace neg terminal, start car. No idea what sort of havoc you would create removing the neg terminal when the car is on.
