3″ Turbo Back Exhaust for 79 Series 4.2L

3″ TURBO BACK EXHAUST FOR TOYOTA 79 SERIES 4.2L LANDCRUISER: 11/1999 – 12/2006

PERFORMANCE GAIN: 15KW / 77NM

Toyota’s 79 Series is a highly capable off-roader and workhorse, but the simplicity of the standard vehicle is somewhat lacking in character. This is where our 3” HDJ79 Performance Exhaust enters the game. Renowned for our Landcruiser range, Torqit’s 79 Series exhaust is one of the thickest and most durable mandrel bent systems of its kind in Australia. With the perfect mix of sound, performance and quality, it has been designed to maximise your vehicle’s power and torque, and generate the ultimate V8 grumble.

To prevent cracking when traversing rough terrain, our 79 Series exhaust is manufactured from 304 grade stainless steel, and up to 2mm thick. The three-bolt laser cut flanges are also 304 grade steel, and welded inside and out to withstand rugged off-roading and long distance touring. The wide diameter and thickness of the HDJ79 exhaust produces a distinctive deep note. If you’re looking to increase your vehicle performance while reducing the noise output, we also offer the option of a muffler. However it’s not just the note that stands out on this system- with a brushed stainless steel finish and laser cut badge, it’s a tailpipe worth showing off.

Bolting onto the back of the turbo, Torqit’s 3 inch exhaust for the 79 Series 4.2L includes high flow catalytic convertors to improve the flow of gases. Double braided flex bellows reduce strain on the system, and absorb excess movement and vibrations. The blue titanium dump pipes on our turbo back systems are unique to Torqit, and help disperse heat and lower the Exhaust Gas Temperatures (EGTs). Titanium is a tough, low-corrosion metal with extremely high heat resistance and a long lifespan. By effectively dispersing heat and cooling rapidly, it keeps the engine bay cooler and protects the engine and its components.

PERFORMANCE EXHAUST FEATURES

Thick Stainless Steel
An exhaust system is exposed to many varied elements, including extreme heat and rough terrain. To handle these harsh conditions, we use stainless steel that is up to 2mm thick to maintain structural strength even after bending. Being extremely durable and difficult to crack, you can go off-road with peace of mind that your Torqit Performance Exhaust system will stay intact. Steel thickness not only affects the strength of an exhaust system, but also the sound it will produce- the thinner the steel, the tinnier the note. As among the thickest mandrel bent systems available in Australia, Torqit Performance Exhausts produce a deep note without cabin drone. Click here to listen to the sound of cheap vs quality stainless steel.

304 Grade Stainless Steel
The highest quality steel used in exhaust systems is 304 grade stainless, which is renowned for its high strength, corrosion resistance, and easy maintenance. It is known as an austenitic stainless steel, meaning due to a high percentage of chromium and nickel it is extremely resistant to rust, stress, and harsh conditions such as high temperatures. The excellent properties of Torqit’s 304 grade stainless demonstrate its strength in comparison to the 409 grade stainless commonly used in the automotive industry. For heavy duty strength and resistance to corrosion, 304 grade stainless steel is the superior choice. A 4WD owner who undertakes water crossings, backs their vehicle into the water to unload a boat, or lives by the coast will especially benefit from our stainless steel systems. Find out more on the difference between 304 and 409 grade steel.

Internal & External Welds
High quality welds are essential to avoiding structural fatigue on joints, stopping cracks from forming, and preventing exhaust gas leaks. All Torqit Performance Exhausts are TIG welded internally and externally, to reinforce the system for maximum strength. TIG welding is complex and more time consuming than the usual MIG welding technique used on exhausts; however it is a key part of creating a premium system. Torqit’s welds are extremely precise, higher quality, and create a beautiful clean finish with no welding spatter.

Mandrel Bent System
Torqit’s Mandrel Bender uses a flexible mandrel rod to support the pipe internally and prevent crinkling as it is bent. This maintains a smooth and constant diameter, improving the efficiency of your engine. With Torqit’s in house mandrel bender, we can maintain the structural integrity and thickness of our systems, prevent restricted exhaust flow, and reduce back pressure. State of the art programming means each exhaust is precisely replicated to follow the correct path, and guarantees accurate fitment. Check out the Torqit Mandrel Bender in action.

Titanium Coated Dump Pipes
Unique to Torqit, our titanium coated dump pipes have extremely high heat resistance. Their aim is to protect the engine and its components by dispersing heat and cooling rapidly. Titanium is a tough, low-corrosion metal, and is significantly more durable than ceramic coatings which deteriorate by chipping, cracking and corroding over time. Torqit’s titanium coated dump pipes have a longer lifespan and maintain their form as the colour gradually vaporizes, leaving a rainbow-like appearance from reacting with heat.

High Flow Diesel Catalytic Converter
Torqit’s high flow catalytic converters focus on increasing exhaust flow, so your engine can breathe more freely and effectively disperse heat to lower your EGT’s. Consisting of a stainless steel case around a honeycomb structure made of various precious metals, our high flow units are 200 CPSI in comparison to the 400 CPSI of standard cats. The reduced CPSI of our cats means they work harder and faster, keeping your vehicle legal while improving power, fuel economy* and overall performance. If your vehicle has been remapped, heavily modified or upgraded with a supercharger/turbocharger, our high flow cats will especially increase your engines power output.

Double Braided Flex Bellows
Flex bellows are an exhaust flex joint, designed to absorb excess movement and vibrations on the vehicles chassis. This prevents strain on the exhaust system, stops cracks from forming, and caters for slight adjustments when aligning and fastening the exhausts flanges. Torqit’s flex bellows are made from 304 grade stainless steel for superior strength, in comparison to the commonly used 409 grade stainless. The double braided design reinforces the bellow to prevent escape of gases, reduces deterioration from heat and gases, and increases the longevity and performance of your exhaust system.

SINGLE EXIT PERFORMANCE EXHAUST INSTALLATION

Torqit’s HDJ79 exhaust is a DIY bolt together system which comes with a full fitting kit. It does not require a hoist, and can be fitted on your driveway in approximately two hours with a basic socket set and spanners.
