Nissan Titan

Every part in this collection fits one application: the Titan XD's 5.0L Cummins V8, sold from 2016 through 2019. That specificity matters more here than it does on a Cummins Ram or a Powerstroke Ford the Titan XD's aftermarket is smaller, so a kit built for a different truck's 5.0L or 6.7L application won't match this chassis, wiring, or ECU calibration. Everything stocked here is scoped to this one platform and these four model years, not adapted from another Cummins fitment.

The lineup covers both ends of a build: standalone EGR, DPF/CAT, and exhaust components for owners piecing together their own setup, EZ Lynk tuning on its own for those who already have hard parts, and the Full Delete Bundle for a matched, ready-to-install combo. None of it kits, tuner, or bundle touches the factory DEF or SCR hardware; every part here works the EGR, DPF, and exhaust side only.

If you're rounding out the exhaust rather than deleting it outright, Diesel Dudes also carries Universal 4-inch and 5-inch Optimal Flow Mufflers, priced at $150 and $175 a smaller add-on worth a look once the delete hardware is installed and you're dialing in sound.

The Nissan lineup is newer and smaller than Diesel Dudes' Cummins, Powerstroke, or Duramax collections, but everything in it is fitted specifically for the Titan XD, not adapted from a different Cummins application.
