Ive been looking a some Hemi Stuff on the 5.7's Truthfully id love to be lucky enough to swap the 3.6 for a 5.7 nothing fancy but budget performance.

Which intake manifold is better for my 2013 Challenger RT 5.7L, Edelbrock Victor 2 or Holly Sniper EFI. Engine is currently N/A, but will be doing later mods.
I would suggest none of those as you really do not need to do anything you'll end up regretting later!

Suggestion #1 See if you are loosing power on your 2013 because your 10 intake manifold bolts are loose, the 2013 torque spec is 105 Inch Lbs for those bolts, tighten them to spec and you should see acceleration improvement, idle smoother, and more performance.

Sharing Regarding the 5.7L Intake Manifold

Suggestion #2 After doing #1 first, get a Diablo tuner either an Intune Platinum or a Trinity, update the tuner through your computer first and then install a 91 Octane tune on your ECM (Engine Control Module) which is unlocked, they did not start locking the ECMs until 2015, so you can write a tune to it.

Suggestion # 1 will cost you buying an Inch Lb Torque Wrench if you don't have one, which you can use later down the road, there are a lot of bolts on the 5.7 that require tightening with an Inch Lb TR.

Suggestion # 2 will cost you buying the tuner, which you will be able to use later if you go further and get written tunes. But hold them horses, don't worry about a written performance tune until you do upgrades to the exhaust so that engine can exhale.

You really need to read read read before you buy anything. Also ask many questions!!
You also need to decide how far that you want to go in modding as it can be easy to waste money and get nothing.

Good luck and have fun.
