Mod that increases sneak attack damage?

[TheWalkingDemon]

The character I play as has the same combat style as Agent 47 from the Hitman series of games, and most of the kills I did in those games was sneaking up behind someone and either putting a hole in their head with a silenced pistol or snapping their neck. As I started to play Fallout: New Vegas, I noticed that I am not going to be able to do this, and it just did not add up, I should be able to kill someone with one hit if I shoot them in the back of the head. Are there any modifications in NV that increase the damage modifier for sneak attack criticals?
