5.9L Magnum Exhaust Q's

Run hedders with 1 5/8 primary tube into true duals 2 1/4 pipe. I have a crate 360 magnum in my 1991 dodge power ram and I run hedman hedders 1 5/8 primary tubes into dual 2 1/4 inch pipe with an H pipe right before the mufflers. And for mufflers I m running flo-tech glass packs that have a 3 inch inside core diameter and are 18 inches long. I know people here don't like glass packs, mainly because they are power robbers, but when you get a glass pack with a 3 inch inside core diameter I don't think that is a restriction. ANd my exhaust doesn't run into anything smaller, it only runs into bigger, the smallest part of my exhaust is 2 1/4 inch pipe.
It runs good and sounds good with this set up and i'm happy with it.
