Aluminized 4-Inch Cat & DPF/SCR Race Pipe Kit for 2016–2019 Nissan Titan (5.0L Cummins)

The Titan 5.0L race pipe from Dieselr is precision-built for the 2016–2019 Nissan Titan XD Cummins platform. Designed for dependable flow and durability, this aluminized 4-inch CAT & DPF/SCR race pipe kit gives your Titan the breathing room it deserves.

Each system is formed from heavy-gauge aluminized steel to resist heat, corrosion, and daily wear. Mandrel bends and welded flanges create a smooth, unrestricted exhaust path for cooler EGTs and consistent performance—whether you’re towing, hauling, or running tuned setups.

Built for clean, OEM-style installation, the kit mounts directly to factory hangers with a tight, leak-free seal. The result is a strong, functional system that performs without compromise and keeps your Titan running steady under load.
