Toyota Fortuner 3.0 D4D 2005-2015 Viper Exhaust System

Toyota Fortuner 3.0 D4D 2005–2015 Viper Full 76mm Performance Exhaust System

Upgrade your Toyota Fortuner 3.0 D4D with the Viper Full 76mm Performance Exhaust System, designed to improve exhaust gas flow, reduce restriction and give your Fortuner a deeper, more aggressive diesel exhaust note.

This is a full 76mm stainless-steel performance exhaust system from the turbo back, including the downpipe, and is specifically designed for the Toyota Fortuner 3.0 D4D 2005–2015 application.

The system is designed to optimise exhaust flow from the turbo through to the rear of the vehicle, making it an ideal upgrade for Fortuners used for daily driving, touring, towing and off-road applications.

Key Features

• Viper Performance Exhaust System
• Designed for Toyota Fortuner 3.0 D4D
• 2005–2015 application
• Full 76mm system
• Stainless-steel construction
• Turbo-back configuration
• Downpipe included
• Improved exhaust gas flow
• Reduced exhaust restriction
• Potentially improved throttle response
• Potentially reduced turbo lag
• Deeper and more aggressive exhaust note
• Vehicle-specific fitment
• Suitable for daily driving, touring, towing and off-road use

Viper describes its turbo exhaust systems as being developed around correct downpipe design and exhaust sizing to improve flow and reduce restriction at the turbo exhaust flange.

Full Turbo-Back 76mm System

Unlike a rear-only exhaust upgrade, this Viper system replaces the exhaust system from the turbo back.

The system includes the downpipe/front section and the remaining exhaust system through to the rear, providing a complete performance exhaust solution rather than only replacing the rear section.

The 76mm diameter provides a larger flow path designed to help exhaust gases move more efficiently away from the turbo and engine.

Downpipe Included

The downpipe is an important part of a turbocharged vehicle’s exhaust system.

Viper specifically highlights the downpipe as one of the most important sections when designing a properly tuned turbo exhaust, as the design and diameter immediately after the turbo influence exhaust flow and back pressure.

This system therefore includes the downpipe as part of the full turbo-back configuration.

Performance & Response

A correctly designed performance exhaust can help reduce exhaust restriction and improve the efficiency of exhaust gas flow.

Potential benefits include:

• Improved exhaust flow
• Improved throttle response
• Improved turbo response
• Reduced exhaust restriction
• Potentially lower exhaust gas temperatures
• Improved overall engine response

Actual results will vary depending on the vehicle’s condition, ECU calibration, turbo condition, intake system, fuel system and other modifications.

No specific horsepower, torque or fuel-consumption increase should be considered guaranteed without vehicle-specific dyno testing.

Deeper Viper Sound

The Viper system also gives the Fortuner 3.0 D4D a more purposeful exhaust character.

Expect a deeper and stronger diesel exhaust note compared with the standard exhaust system, while retaining the practicality required from a Fortuner used as a family, touring or off-road vehicle.

Built for Touring, Towing & Off-Road Use

The Fortuner 3.0 D4D is well suited to touring and adventure applications.

The Viper 76mm system is ideal for vehicles used for:

• Overlanding
• Long-distance touring
• Caravan towing
• Trailer towing
• Camping
• Gravel-road driving
• Off-road use
• Daily driving
• Performance upgrades

A freer-flowing exhaust can be particularly useful when the vehicle is operating under sustained load, such as towing or travelling through demanding terrain.

Important: This application is for the 3.0 D4D engine, not the later 2.4 GD6 or 2.8 GD6 Fortuner.

South African Specification Vehicles Only.

Before requesting a quotation or placing an order, please provide:

• Vehicle year
• Exact Fortuner model
• Engine specification
• 3.0 D4D confirmation
• 4×2 or 4×4
• Transmission where relevant
• Existing aftermarket exhaust details
• Long-range fuel tank details
• Auxiliary fuel tank details
• Any other underbody modifications

Existing Aftermarket Exhaust

If your vehicle already has an aftermarket exhaust, please specify the brand and configuration in the order notes.

This is important because an existing aftermarket exhaust may require a different fitment approach or may affect which sections of the Viper system are required.

Please specify if the vehicle has:

• Existing aftermarket exhaust
• Existing downpipe
• Modified front exhaust section
• Modified intermediate section
• Modified rear section
• Aftermarket catalytic converter
• Other exhaust modifications

Long-Range & Auxiliary Fuel Tanks

If your Fortuner has an aftermarket long-range fuel tank, auxiliary tank or additional underbody equipment, please specify this when requesting a quotation.

Additional equipment underneath the vehicle can affect:

• Exhaust routing
• Exhaust-to-tank clearance
• Heat clearance
• Chassis clearance
• Suspension clearance
• Tailpipe positioning

Fitment must be confirmed where an aftermarket tank or other underbody modification is installed.

Full 76mm turbo-back performance exhaust system with downpipe included.

This is a complete performance exhaust system rather than a rear-only or tailpipe-only upgrade.

Viper’s turbo exhaust design approach emphasises the importance of correctly engineered downpipes and appropriate exhaust diameter rather than simply fitting a larger pipe to the vehicle.
