2021 ST Rear Differential

[MRV568]

I have purchased a 2021 Explorer ST with a little over 100,000 miles on it. It is bone stock and has the 2 bolt rear differential. I hear alot about
these vehicles needing a brace on the differential. Is the 2 bolt sufficient or does the 2 bolt still need a aftermarket brace? Thanks for any input...

2 bolt is perfectly fine as is.

Would the 2 bolt be ok with a aftermarket thermal exhaust and a mild tune, or would the brace be required at that point?

the exhaust will not add HP. The tune will but you will
be fine as is.
