I installed GT 500 take-off mufflers and a K&N flat filter. Do I need to get a tune now?

No. Not required.

AND YES AS A MATTER OF FACT I DID CHECK TO SEE IF IT WAS A COMMON QUESTION!

Okay, that is part of his sig, don't take offense to it. The answer is no.

Not required but stick with the stock paper filter.

How come?

CMcNam

It filters just as well as a K&N, perhaps better. Any negligible increase in airflow provided by the K&N is not utilized unless the car is tuned to compensate for it. I don't think the K&N provides any more airflow over the stock filter anyways, but hopefully someone with more knowledge on the subject chimes in.

That pretty much sums it up plus in testing the K&N lost power over the stock filter. Regardless you can spend your money more wisely somewhere else.
