Exhuast Brake for 7.3 PS. Who’s got them and what kind

As much as I would love a new dually its just not gonna happen in the next couple of years. I love my F250 7.3, pulls like an animal but the brakes are the weak link now that we have our 39′ toy hauler.

Been looking at adding an exhaust brake and today spoke to one of the top diesel dogs in our area and he said the best one for my truck would be a PacBrake PRXB. He said he’s run US Gear, Banks and others and this is by far the best one he has run on his 7.3

Before I drop 2k on a unit and install just curious who is running exhaust brake on a 7.3 Powerstroke
