Nissan Pathfinder R51 2.5L YD25 Turbo Diesel 2006-On 3" Dump Pipe TNAV25-73SS 

TNAV25-73SS turbo dump pipe is an Australian-made performance exhaust upgrade designed for Nissan Pathfinder R51 models fitted with the 2.5L YD25 turbo diesel engine.

This application suits automatic models from 06/2006-on and manual models from 05/2007-on. Manufactured from 409 stainless steel, the TNAV25-73SS uses 3.00" (76mm) pipework with a 3" flex section and provides a straight-through exhaust path from the turbocharger.

The dump pipe is designed to bolt directly to the DPF or compatible DPF-delete pipe.

AUTOMATIC MODELS – Sensor/computer modifications are required for the vehicle to run correctly with the 3" straight-through pipe.

Construction

TNAV25-73SS is manufactured from 409 stainless steel using 3.00" (76mm) pipework with a 3" flex section. The mandrel-bent construction helps maintain the internal pipe diameter through bends for improved exhaust gas flow.

The 409 stainless steel construction provides good corrosion resistance and durability for the high-temperature operating conditions found in turbo-diesel exhaust systems.

What's Included

1 x TNAV25-73SS 3.00" (76mm) stainless steel turbo dump pipe with 3" flex section.

Why Upgrade the Turbo Dump Pipe?

The dump pipe carries exhaust gas directly away from the turbocharger, making it an important section of a turbo-diesel exhaust system. Restriction immediately after the turbo can affect how efficiently exhaust gases are discharged into the remainder of the exhaust system.

The 3.00" (76mm) straight-through TNAV25-73SS provides a larger exhaust path to help reduce exhaust restriction. When used as part of a correctly designed exhaust system, improved flow after the turbo can assist turbo response and overall engine performance.

Installation Tips

Apply penetrating lubricant such as WD-40 or similar to turbo and exhaust fasteners before removal to assist with dismantling components that have been subjected to prolonged exhaust heat.

Inspect the associated gaskets, fasteners, flex connections and exhaust mounting components during installation and replace worn components where required.

For automatic vehicles, the required sensor/computer modifications should be addressed as part of the installation.

Warranty & Compliance

TNAV25-73SS is designed as an aftermarket performance exhaust component for the listed Nissan Pathfinder R51 YD25 applications. Installation and use must comply with applicable emissions, vehicle modification and road regulations in your Australian state or territory.

Removal or modification of emissions-control equipment, including the DPF where originally fitted, may not be legal for road use.
