Hit rev limiter
Yesterday driving home in my 12' GS w/ headers, off road pipe & NPP, I nailed it at about 65 mph, trans was in S, now I'm not sure if I bumped the paddle or what but this thing screamed up to red line hitting the limiter. At first I thought I blew the engine as it was so loud with the NPP, or thought I exploded a muffler. Either way the car obviously acted as designed, fuel shut off & spark pulled back or whatever it should be called. The car sputtered for a second or 2 & returned to normal driving, I should be just fine correct?

Have hit it numerous times in my GF's 2010 GS (A6) and it's fine. Stupid paddle shifters are so slow to respond when using them and trying to get every rpm. Definitely on the list to "tune" once some headers and intake go on her car.

The paddles will always be slow to react, unfortunately

A very good transmission tune will make the paddles work quite well, and you wont have to do the shift and wait routine. Not something you can do with the normal tune software. Chuck COW and ECS are the only ones I have felt that seem right.
There is also some changes in shift firmware and trans. pressure settings between years.
IMHO some tuners raise the rev limit a bit much.

As you nailed it hard at 65 there's a good chance the trans dropped into 2nd gear which then redlines very quickly. Bouncing off the limiter is fairly common, especially in autox where you may not want to shift prior to an upcoming corner. So, no harm there.
Next time, use the paddles to downshift into 3rd and take off from there. You'll have much better control.

Don't know what's being changed but can confirm whatever it is works from my own eyes.
