Posting here cause more performance related - diffuser or valence?

I have A 2010 SS that's has all bolt ons, headers, cammed and have American thunder cat back with quad tips through NPP diffuser.

However, I've noticed my valence/diffuser has started to bow in the middle bottom. I'm guessing because as I go past the speed limit (who, me?) it's just catching air in that pocket. It's not really a diffuser at all to me, more of a valence.

Question is, what's the remedy? Go ZL1 with actual diffuser or?

What are the options at this point or am I over thinking the issues this may be causing with catching air?

Thinking its just the age of the plastic, myself I am thinking of getting a aftermarket painted smoothed rear diffuser that's metal I think looks good.

Get a big piece of cardboard and play with it and then have a metal shop cut it out for you.
