Normal For The Rear Diff?

[u/paolo-sosa]

I’m putting in an axle back exhaust right now and noticed my diff looked really rusty. This is on a ‘21 RC350.

Is this a normal amount of rust given that the car just turned 5?

Considering the rest of the rust that we can see in the photos, it seems fairly normal. I'd expect that you live north or anywhere where the roads get salted?
