RE: APR Stage 1+
I personally would say its pretty necessary. Theres more fuel/air to be burned off in the combustion process and you dont want your stock exhaust restricting those gases fromgetting expelled.
Even with just a regular chip you should upgrade your exhaust to take full potential.

harmful or not as good as it could be.. I am going to get exhaust eventually.. i just want to get the injectors and stage 1+ first. Can I do it 6 months before or do I have to wait until I get exhuast?
