Thick Stainless Steel

An exhaust system is exposed to various elements, including extreme heat and rough terrain. To handle these harsh conditions, we use stainless steel up to 2mm thick to maintain structural strength even after bending. Being incredibly 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 affects not only the strength of an exhaust system, but also the sound it will produce- the thinner the steel, the tinnier the note. Among Australia’s thickest mandrel bent systems, 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, 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 highly resistant to rust, stress, and harsh conditions such as high temperatures. The excellent properties of Torqit’s 304-grade stainless demonstrate its strength compared 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 significantly 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.
