Do I need an Fuel Injection Controller to run an exhaust?

Hey guys,

Sorry if this is a stupid question or if this is answered elsewhere.

I'm thinking of getting the M4 exhaust and I just wanted to know if I needed a fuel injection controller / tune of some sort of if I could use the stock settings.

Obviously it would make more power and be better if I had the fuel injector, but I'm just trying to figure out if i can do it in stages or if it should really be done all at once.

Thank you!
