So after coming down the mountain with a plethora of oak, my service engine light came on. Drove to the nearest O'Reilly and pulled a P0420 code for insufficient flow with the catalytic converter. Is that a common issue with there? Or is it possibly a different issue? Thanks for your help!!

Cats are dying or your manifolds are cracked, cracked manifolds are pretty common. How many miles do you have? OEM cats are gonna cost about 3-4k, JBA longtubes, Cajun bpipes and Uprev are going to be way less, almost half the price.

Its 09 with 135k on it

I would suspect cracked manifolds. Talk to the guys at cajunbpipes
