As soon as you replace that header it is really going to be loud. You need to think a better approach that just swapping parts. Research around for the companies that provide complete tuned cat-backs. If replacing the header, go with just the Weapon R . It has a custom fitted s-pipe and is a 4-2-1 design. Invest in proper fit resonator and don't go larger that 2.25" ID pipe NA unless you going to be doing some major power mods.
