Toyota Fortuner 2.8 GD6 2016+ Viper Full 76mm Performance Exhaust System

Upgrade your Toyota Fortuner 2.8 GD6 with the Viper Full 76mm Performance Exhaust System, designed to improve exhaust gas flow, reduce restriction and deliver a deeper, more aggressive exhaust note.

Specifically developed for the Toyota Fortuner 2.8 GD6 from 2016 onward, this full 76mm stainless-steel turbo-back exhaust system provides a performance-focused upgrade for daily driving, touring, towing and off-road applications.

With a larger-diameter exhaust path and stainless-steel construction, the Viper system is designed to allow the turbo-diesel engine to evacuate exhaust gases more efficiently while giving the Fortuner a stronger performance character.

76mm Performance Exhaust Design

The 76mm diameter exhaust system provides a larger flow path compared with the standard exhaust system.

The Viper system is designed to optimise exhaust gas flow and reduce back pressure, allowing the turbo-diesel engine to operate with a less restrictive exhaust path.

This can be particularly beneficial when the Fortuner is being used under increased load, such as when towing, carrying additional touring equipment or travelling through demanding off-road terrain.

Improved Turbo-Diesel Response

A freer-flowing exhaust system can complement the Fortuner 2.8 GD6’s turbocharged diesel engine by helping exhaust gases move more efficiently through the system.

Potential benefits include:

• Improved exhaust flow
• Sharper throttle response
• Improved turbo response
• Reduced exhaust restriction
• Potential reduction in exhaust gas temperatures
• Improved overall driving feel

Actual results will depend on the condition and specification of the vehicle, as well as other modifications and ECU calibration.

Deeper Viper Exhaust Sound

The Viper system is also designed to give the Fortuner 2.8 GD6 a more purposeful exhaust note.

Compared with the standard system, the upgraded exhaust delivers a deeper, stronger and more aggressive diesel sound, adding character without changing the Fortuner’s practical SUV capabilities.

The Viper range offers different sound characteristics, allowing enthusiasts to select an exhaust setup suited to their preferred sound level.

409 Stainless-Steel Construction

The system uses 76mm 409 stainless steel, providing a durable construction suited to the heat, vibration and environmental conditions experienced by an exhaust system.

Stainless-steel construction also provides improved corrosion resistance compared with conventional mild-steel exhaust components.

Viper Performance Exhaust systems are precision-engineered using techniques such as mandrel bending and precision welding to help achieve consistent flow and accurate fitment.

Built for Touring, Towing & Off-Roading

The Fortuner 2.8 GD6 is commonly used as a family SUV, touring vehicle and 4×4 adventure platform.

The Viper 76mm exhaust is well suited to Fortuners used for:

• Overlanding
• Long-distance touring
• Caravan and trailer towing
• Camping and adventure travel
• Gravel-road driving
• Off-road use
• Daily driving
• Performance-focused builds

The improved exhaust flow can be particularly useful when the vehicle is working harder under sustained load.

South African Specification Vehicles Only.

Because Fortuner exhaust configurations can vary between model years and vehicle specifications, the exact vehicle application should be confirmed before ordering.

Existing Aftermarket Exhaust

If your Fortuner already has an aftermarket exhaust system, please specify this in the order notes when requesting a quotation or placing your order.

Existing exhaust modifications may affect compatibility, installation requirements and the final exhaust configuration.

Long-Range & Auxiliary Fuel Tanks

If the vehicle is fitted with a long-range or auxiliary fuel tank, this must be disclosed before fitment.

Additional underbody equipment can affect:

• Exhaust routing
• Exhaust-to-tank clearance
• Heat management
• Chassis clearance
• Suspension clearance

Compatibility should therefore be confirmed before installation.

HJM Offroad can supply and fit the system as part of your Fortuner’s performance and 4×4 upgrade.

A performance exhaust is designed to improve exhaust flow and reduce restriction, but actual performance results will vary between vehicles.

Factors such as vehicle condition, ECU calibration, fuel quality, turbo condition, supporting modifications and vehicle usage can influence the final result.

The exhaust system should not be considered a guaranteed horsepower or torque increase without vehicle-specific dyno testing.
