I would assume so, if the pipes were the same size and there was enough room for the muffler. I would suggest contacting Borla

Borla 400286 ProXS Muffler Metallic, 4 inch

Q: Will this work on a 2001 Silverado 2500hd 8.1L that already has a borla exhaust

Nope, the exhaust cfm of a 496 needs 3" duals to have less back pressure.
