Dieselr Aluminized Downpipe Back Exhaust | Nissan Titan Cummins 5.0L 2016-2019

DIESELR Downpipe-Back Aluminized Exhaust System (2016–2019 Nissan Titan XD Cummins 5.0L)

Built for Nissan Titan XD owners who demand performance and precision, the DIESELR Downpipe-Back Aluminized Exhaust System replaces the restrictive stock exhaust with a free-flowing 4" or 5" mandrel-bent system. Designed specifically for the 5.0L Cummins platform, this system improves throttle response, increases torque, and gives your Titan a deeper, more aggressive tone without excess drone.

Crafted from heavy-duty aluminized steel, each section is mandrel-bent for smooth exhaust flow and long-term durability under high-heat conditions. The system includes reinforced flanges, pre-welded hangers, and premium clamps — ensuring a secure, factory-style fit. The included straight-through muffler provides balanced backpressure and a refined race-style sound that complements daily driving or towing applications.

This system bolts directly to OEM hangers for a clean install and requires no major modifications. Engineered for off-road and competition use, it’s the ideal upgrade for drivers looking to bring true Cummins character to the Titan XD platform.
