Default Recommend kernal for my AOSP rom I am using? (exfat support)

I just went from 4.1.2 to 4.4.4 Dirty Unicorns Rom using Philz recovery. Everything seemed working fine, no gps locking problems, but it will not recognized my 64 gb exfat formatted sd card.

Can someone recommend me a kernel I can flash? Or at least another TW based Rom? It's my understanding that they have native exfat support.
