The 3.5″ exhaust for Nissan Navara D23 NP300 2.3L YS23 (DPF back) by Outback Exhausts is an Australian-made performance system engineered to improve flow, durability and exhaust note without removing the factory DPF. Manufactured from high-grade 409 stainless steel and fully mandrel-bent, it delivers smoother gas flow, improved responsiveness and a deeper tone.
Designed specifically for the Nissan Navara D23 / NP300 2.3L YS23 twin-turbo diesel, this system provides a straightforward bolt-on upgrade using the factory mounting points. It pairs perfectly with professional ECU remapping and tuning services from Sunshine Coast Diesel Tuning.
