Flowmaster hp gains?

Does anyone have an estimate of how much rwhp gains dual flowmaster AT with an h-pipe typically gets?
The dual flowmasters make less hp that a single flowmaster would, right?

Maybe it's placebo but I swear I picked up some horses with just the muffler change. Something in the area of 5-10 I would guess.

10RWHP would be good for just a muffler swap. I don't doubt it either the way it runs now.

The slowmaster...I mean "flowmasters" feel like I may have lost power-or atleast not have gained any.
