Hey all. I am still new here.

I currently have an 07 NFR, mods currently are modified stock intake, 63mm test pipe and uk modded exhaust, and hondata tune.

I just purchased a 70mm invidia test pipe and greddy single rs exhaust.

My question is since I am going from a stock "modded" exhaust with 63mm test pipe to a 70mm test pipe mated to a 70mm single exhaust should I have the car retuned?

I'm very new to the hondata so learning a lot.

You don't need to get the car tuned, however it'd be useful to do so because you've opened up airflow quite a bit, and can only benefit from getting a new tuned dialed in. You'll be able to squeeze out a few ponies with a tune as well.
