The 78 Series Troop Carrier is an extremely capable 4WD, ideal for towing, touring and withstanding rugged off-roading. Renowned for our Landcruiser range, the 3.5” 78 Series Landcruiser Performance Exhaust is one of the thickest and most durable mandrel bent systems of its kind. This Troopy exhaust is the first 3.5” system introduced for this model in Australia, and the largest diameter available on the market. Extensive R & D has produced the perfect mix of power, torque, and a deep V8 note.

Starting from the back of the DPF, Torqit’s 3.5 inch Troopie exhaust takes a unique path beneath the vehicle with a spectacular piece of the brushed steel exhaust visible under the sidestep. Manufactured from 304 grade stainless steel and up to 2mm thick, the 78 Series exhaust is built for strength to prevent cracking when traversing rough terrain. The three-bolt laser cut flanges are also made from 304 grade steel, and welded inside and out to withstand heavy duty off-roading and long distance touring. Coming standard with a resonator to maximise sound output, the wider diameter and thickness of the exhaust adds depth and rumble to the note.

As the owner of a vehicle with a DPF, no doubt you are aware of how damaging excessive exhaust gas temperatures (EGT’s) are for a diesel engine. Torqit’s DPF Back Performance Exhaust for the 78 Series Troop Carrier aims to lower these EGT’s by improving the flow of gases, and increasing your engine’s efficiency and fuel economy.* As it bolts straight onto the DPF, Torqit’s Troopie exhaust complies with all insurance and warranty requirements. It is the ideal alternative to deleting your DPF, without the legal ramifications.


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.

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.


Torqit’s 3.5 inch Troopie Performance Exhaust is a bolt together system, and comes with a full fitment kit and detailed instructions. It takes approximately three hours to install, for which reason we recommend fitting on a hoist at your local Torqit dealer.
