You might in in for a nice surprise, I pulled 355 -rwhp with a chip and Borla exhaust, put on stainless works headers 2" prim and B&B with their X-pipe then pulled 390-rwhp I like B&B's X-pipe the sholder joint "where they meet" is around 6" long together I seen some other X-pipes that looked to be only a inch at the joint, besides the 3" inch pipe will move more air in the long run.
