I've straight piped my 06 2500 Hd but how do you get by smog inspection with out the catalytic converter? I'd love to do a complete system with out it, I'm running the Edge Juice with attitude and it is OUTRAGEOUS in #5 but not alot of Turbo sound except when the waste gate is opening, What kind of Breather is best and won't set off my Computer?
Where do you live that you have smog inspections? Diesels are emissions exempt in PA and most other states. There is no wastegate on an LBZ. Definitely get a dry flow.

Remove the resonator on the intake and block the egr. this will make it louder.
