Twin Exit Exhaust for Toyota 79 Series 4.5L Dual Cab Landcruiser: 08/2012 – 07/2016
Performance Gain: 23KW / 91NM
The Toyota 79 Series is an iconic old-school vehicle, which really lives up to its reputation as a tough, functional workhorse and off-road tourer. Although often dubbed as one of the most reliable heavy duty Utes available, the standard design is extremely simple and somewhat lacking in character. This is where Torqit’s 3.5” Twin Exit Performance Exhaust for the 79 Series dual cab enters the game. Renowned for our Landcruiser systems, Torqit has put in extensive R & D to deliver the perfect mix of sound, performance, and quality.
Designed for maximum power and torque, the turbo back 79 Series dual cab twin exhaust is one of the most thick and durable mandrel bent systems of its kind in Australia. Tried and tested in the toughest of Australian conditions, it is manufactured from 304 grade stainless steel and is up to 2mm thick to prevent cracking when traversing rough terrain. The three-bolt laser cut flanges are also manufactured from 304 grade steel, and are welded inside and out for extra strength to withstand heavy duty off-roading. The thickness and diameter of the 79 Series 3.5” exhaust produces the ultimate deep V8 rumble, while the twin exit creates a different dynamic to the note. It’s not just the note that stands out on this system- it comes with a brushed stainless steel finish and a dual left and right exit, which are visible from the rear wheel back on both sides.
The system is a 3.5” from the back of the turbo and runs into 3” tailpipes. It includes high flow catalytic converters to improve the flow of gases, and double braided flex bellows which reduce strain on the system and absorb excess movement and vibrations. The blue titanium dump pipes help disperse heat and lower the Exhaust Gas Temperatures (EGT’s). 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.

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 flanges used in 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.
PERFORMANCE TWIN EXIT EXHAUST INSTALLATION
The Torqit 3.5” Twin Exit exhaust for the 79 Series dual cab is a bolt together system, which comes with a full fitting kit and takes approximately three hours to install. While DIY fitment of this exhaust is possible, it may be hard to reach the turbo without a hoist. For this reason we recommend fitment through an authorised Torqit dealer.
