76mm Performance Exhaust Design

The Viper system replaces the factory exhaust with a full 76mm stainless-steel system from the turbo back.

The larger-diameter exhaust is designed to provide a less restrictive path for exhaust gases, helping the turbocharged 2.4 GD6 expel exhaust gases more efficiently.

Improved exhaust flow can contribute to a more responsive driving experience, particularly when accelerating, towing or driving under heavier loads.

Viper specifically lists improved performance, reduced fuel consumption, reduced exhaust gas temperatures on turbo vehicles and improved sound among the benefits of its performance exhaust systems.

Improved Hilux 2.4 GD6 Sound

The Viper performance exhaust also changes the character of the Hilux.

Expect a deeper, sportier and more purposeful diesel exhaust note compared with the standard system.

This makes the exhaust particularly suited to Hilux owners who want their vehicle to sound more like a properly built performance 4×4 while retaining its practical touring and everyday-driving capabilities.

Built for Touring, Towing & Off-Roading

The Hilux 2.4 GD6 is commonly used for a combination of daily driving, work, towing, recreational 4×4 and overlanding.

The Viper exhaust can complement a vehicle equipped with:

• Bull bars
• Suspension upgrades
• Larger all-terrain tyres
• Snorkels
• Roof racks
• Canopies
• Drawer systems
• Long-range fuel tanks
• Recovery equipment
• Towing equipment
• Camping and overlanding accessories

Improved exhaust flow can be particularly useful when the vehicle is working harder under load, although actual performance depends on the complete vehicle setup.

Vehicle specification and factory exhaust configuration should always be confirmed before ordering, particularly where the vehicle has been modified. HJM’s current listing identifies the broader application as Toyota Hilux GD6 2016–2025.

Important Fitment Information

• Designed specifically for the Toyota Hilux 2.4 GD6.
• South African Specification Vehicles Only.

Existing Aftermarket Exhaust & Modifications

If your Hilux has already been modified, please provide these details before ordering.

This includes:

• Existing aftermarket exhaust
• Downpipe modifications
• Exhaust modifications
• ECU tuning or remapping
• Performance chips
• Modified intake systems
• Intercooler upgrades
• EGR modifications
• Other engine-performance modifications

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

An exhaust system can be fitted as a standalone modification, but the final configuration should always be considered together with the vehicle’s existing hardware and calibration.

Long-Range & Auxiliary Fuel Tanks

If your Hilux is equipped with an aftermarket long-range fuel tank, auxiliary fuel tank or other underbody accessories, please advise HJM Offroad before fitment.

Additional underbody equipment can affect:

• Exhaust routing
• Pipe clearance
• Heat clearance
• Suspension clearance
• Fuel tank clearance
• Tailpipe positioning

The complete vehicle configuration should be checked before installation.

A performance exhaust is designed to improve exhaust flow and reduce restriction, but actual results will vary depending on the vehicle’s condition, mileage, fuel quality, ECU calibration, turbo condition, intake system, vehicle load, tyre size and other modifications.

Viper lists improved performance, fuel consumption and reduced EGTs on turbo vehicles as potential benefits, but specific power, torque or fuel-consumption gains should not be regarded as guaranteed.
