well with dtlt I'd go a head and cut flange off put v band in place on headers . custom make x pipe in place of y pipe. v bands, 4" flex pipe with two resonators in too x pipe, 2 more sets of v bands. gonna be hard to stuff two big mufflers between drive line and frame. gonna have to go with duel in and duel out muffler. then in back gonna have to work around spare tire. on mine had to drop spare and throw it in the bed. I used 2.5" from manifolds back. glass packs after the x pipe and some big 3" fart cans on the exit. mine still needs some resonators and flex pipe. I'm using the aero turbines resonators. that's just my input.
