Default 2-stepping questions

Hi guys, I had a few questions about getting a 2-step system.
first: Do I need test pipes? I have read that it isnt a good idea to have a two step system while running cats.
second: would i need to upgrade the headers?
third: whats the best rpm to launch at? (NA motor)

the best rpm is the one you determine for your tires and your street conditions

2 step is just a rev limiter. has no/minimal effect on the cats. 2 step is not antilag, which will kill your cats.
