Manolescu and Piccirillo introduced RBG links, a kind of 3-component framed links in S^3, that produce knot pairs with the same 0-surgery. In this talk, I will define n-RBG links, which generalizes their RBG construction to n-surgeries. I will explore the potential use of the s-invariant to detect exotic pairs of definite 4-manifolds from specific types of n-RBG links.
