Im not an expert but your exhaust might be to free flowin for the mods you have done to it. Resulting in a low end loss. I have LPP longtubes 90% TQ managment removed and mine will powerbrake, I have a single 3in pipe to a 40series flowmaster, which I know isnt the best muffler. I could powerbrake even before the headers though.
