Turbo Back Exhaust – Nissan Navara D40 Spanish Built 2.5L YD25 (2011-2015)- Outback Exhausts

Overview

This 3 inch turbo back exhaust system is engineered specifically for the Nissan Navara D40 Spanish-built 2.5 L YD25 (2011–2015). Built in Australia from mandrel-bent 409 stainless steel, it replaces the entire factory exhaust from the turbo outlet through to the tail pipe. By reducing restriction and improving exhaust flow, the system helps the turbo spool earlier, boosts mid-range torque and enhances throttle response. It is a reliable upgrade for touring, towing and off-road use.

Designed for the Series 4 140 kW YD25 Navara, this exhaust uses the factory mounting points and follows a complete bolt-on configuration. Installation is straightforward with standard workshop tools. When combined with a custom ECU tune from Sunshine Coast Diesel Tuning , the upgrade can provide noticeable increases in drivability. Refer to the manufacturer’s product information on Outback Exhausts for further specification details.
