Depending on state emissions, you may have to retain the factory cats, which isn't a bad thing on the v6's. I'd personally add divorced duals right after the cats into chambered mufflers (flowmaster 40's, borlas or pypes stree pros), and either dump with turndowns under the car or exit out stainless steel, NOT chrome tips.
You don't need a GT bumper for tips but it does look better imo.
