What would be louder H-pipe or Prochamber?

What would be louder?

I just got rid of my Pro-Chamber, actually in the trunk of my daily driver, and went with MAC Long Tube Headers and a Shorty off road H Pipe.

Would I of gotten a louder sound if I went with a shorty Pro Chamber after the Long Tubes and would I also get more power as well?

I have 2 Chamber Flowmasters and love the sound of them and really don't want to swap out mufflers to get a louder sound...I want to keep my 2 Chamber Flowmasters.

Not sure if I should get rid of the Shorty H-pipe also from MAC and just put in a Shorty Pro-Chamber....reqason I went with the H-pipe is the fact that I thought the air would flow quicker since no restriction or Chamber box and I also hear that the flowmaster sort of are restrictive so I wanted less restriction so I choose the Shorty H-Pipe. I like a deep louder sound and was wondering if the Shorty Pro Chamber would provide that over the Shorty H pipe I now have on without losing any power. Would I gain HP by switching out the Shorty H-pipe to a shorty Pro Chamber and @ chamber Flowmasters?

Appreciate the thoughts.

O/R H will be louder than the Prochamber

Really? Hmmm, even with my turn downs right after the mufflers the prochamber isn't very loud at all.

I have the prochamber and love the sound of it. How loud is it ? Well, I've heard louder but I've also heard quiter too. It all depends on what you like.

EDIT: I just noticed you're running flowmasters. In that case, the h-pipe will give a mean rumble down low but that prochamber will scream and roar at WOT.
