Dieselr 4",5" Downpipe Back Single | Nissan Titan Cummins 5.0L 2016-2019

The DIESELR Downpipe-Back Exhaust System for the 2016–2019 Nissan Titan XD Cummins 5.0L is engineered to replace the restrictive stock exhaust with a free-flowing 4" or 5" system. Built from aluminized steel and mandrel-bent for smooth airflow, this kit is designed to improve throttle response, torque, and overall drivability while giving your Titan the aggressive tone it deserves.

Each kit includes pre-welded contour-bent hangers, reinforced flanges, and all clamps required for installation. With a direct-fit design that mounts to OEM hangers, installation is straightforward without unnecessary modifications. A straight-through muffler is included for balanced tone and performance.

This is a race-style downpipe-back kit intended for off-road/competition use only.
