You never said what vehicle but I'm going to assume its a Avalanche? I have an Av also and for as big as it is there is really not a lot of room under the truck which really limits the muffler and exhaust configurations.
Personally I think you should wait for the supercharger before installing a 4" exhaust. How do you plan on running the exhaust? dumped? single out? I cant imaging being able to snake a 4" pipe around the rear axle to exit behind the tire, unless your Av is lifted.
Below are my suggestions on Mufflers, if you are a Amazon prime member they have free return shipping....clamp the muffler on the truck, go for a spin around the block, if you don't like the muffler clean it up and ship it back!

ok here is some exhaust comparisons for you all...
stock manifolds and stock cats... just a custom stainless cat back 3 inch with borla XR-1 5 inch round case muffler...
05 avalanche 5.3 with 3 inch stainless borla XR-1 exhaust - YouTube
full length headers with ORY into the same exhaust only with an 18 inch case bullet resonator in front of the XR-1
borla xr-1 with full length headers and no cats with bullet resonator - YouTube
and now finally i have a solo performance MACH straight through muffler on there... MUCH quiter but still has a deep nasty tone once i get into it. SO FAR I LOVE IT!!!!... i have only 250 miles on the muffler now... and i still have the bullet in front of this muffler but i want to wait till about a 1000 miles to let this muff break in and see how loud it is before i decide if i want to take the bullet resonator off to make it just right...
