Theres no delete kit that will pass. Any delete kit you put in place will fail the visual. Anything that disables the DPF/EGR fill fail the OBD test. And both the above will cause you to fail the snap test.
That said, there are three groups. Those that say screw it and delete it anyway reverting back to stock for emissions and dealer visits. Those that go stealth and buy a second DPF/CAT, hollow it out and run that except for emissions and dealer visits. And those that run a DPF on tuner which is CARB compliant so they don't have to mess with it.
As to what you can do. If your looking to just disable the DPF and EGR's and gain the mileage, look at the DPF-R+. If your looking for more power as well, look at the H&S, Spartan or custom tunes on an SCT. Cost will be anywhere from $600-$2k for tuner and parts.
