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

Overview

This 3 inch turbo back exhaust Navara D40 YD25 system by Outback Exhausts is designed specifically for the Thai-built Series 3 2.5 L turbo diesel dual cab manual, produced from 2011 to 2015. Replacing the entire system from the turbo outlet to the tail pipe, it provides a less restrictive exhaust path for improved flow and a deeper exhaust note.

Manufactured from 409 stainless steel, this system offers excellent heat resistance and long-term durability. The precise mandrel bends, strong welds and accurate fitment ensure reliable performance for touring, towing or daily driving.

Key Features

• Made in Australia from 409 stainless steel for durability and heat resistance.
• Mandrel-bent 76 mm tubing for consistent diameter and optimal exhaust flow.
• Supports performance gains when paired with ECU tuning.
• Direct bolt-on installation using factory mounting points.
• Does not normally require a hoist for installation.
