Borla Exhaust Part #140776BC

New to the forum. Hello!
I have a 2021 GMC Sierra 1500 AT4 Crew Cab.
Wanting to order aftermarket exhaust and before I place the order, I wanted to get feedback on the correct part # to order. Some performance sites like Summit show that it doesn't fit.

Does anyone have this on their truck currently or 140776CF?

I'm currently running the 140776BCF from Borla. Fit and finish was perfect.

Cannot help you with part number aftermarket, got mine thru GM with GM install to retain complete factory warranty and it extended to the exhaust as well. Very happy with it!
