Legendex – Premium Offroad Performance has taken the Australian 4WD exhaust industry by storm, launching off the shoulders of Genie Performance Exhaust with a history of more than 50 years of exhaust manufacturing in Australia.

As the brainchild of CEO Barney Lewis, a hole in the market was identified for a 4WD exhaust that stood up to the rigours of 4WDing in Australia.  Legendex believes they produce the toughest 4WD exhausts in Australia, and also back them up with a 10-year offroad warranty.

Complimenting their exhausts, they also offer a range of performance upgrades for modern 4WD’s, including throttle controllers, power command modules,  & engine remapping. As well as other accessories such as catch cans, fuel filters, snorkels & rocksliders.

Check out all the unique features that make Legendex tough…

Ceramic Coated Dump Pipes

Rapidly transfers the high exhaust temperatures out of the engine bay for cooler engine operating temperatures, cooler air intake and greater power. The coating also greatly extends the durability and life of the dump pipe by reducing extreme heat cycling metal fatigue. The coating reduces the exterior temperature by 110-120c. Pyro (EGT) fittings in the dumps are standard.

PLUS Legendex dumps are manufactured 30% thicker than most other dump pipes.

Polished Stainless Long Life Mufflers

Heavy glass wool packing contained by stainless wool lagging inside the mufflers ensures they never need to be re-packed. In the cut-away photo above, the stainless wool has been peeled back to show the stainless perforated tube beneath. Mufflers are straight through with all stainless internals prevents corrosion.

Heavy Duty Flanges

The 10mm thick flange system provides maximum strength and the low-profile 2-bolt system doesn’t suffer from the clearance issues that 4-bolt flanges can have.

High-Spec High-Flow Cats

High flow diesel specific catalytic converters come with a 10-year warranty and a 200 cell stainless-core diesel catalytic converter built from stainless steel plus stainless heat-shield. The only cat in Australia that carries a 10-year warranty.

Ultra-Strong Rod Hangers

Legendex developed a collar system for hangers using a 12mm rod and a collar that wraps the tube. This collar absorbs vibrations and strengthens the tube.

409 Stainless Steel Tube

Mandrel bent 409 stainless tube is the superior choice for exhausts. This OEM grade stainless steel delivers the best corrosion resistance PLUS maximum heat cycling tolerance. Higher grades of stainless don’t tolerate heat cycling – they get brittle and crack. Aluminised mild steel handles the heat-cycling but has inferior corrosion resistance as it melts and breaks down with high exhaust temperatures. 

 

 

Ultra-Strong Flat-Bar Hangers

Legendex developed an exclusive 270-degree gripper system to absorb vibrations and using 5mm flat-bar hangers to be ultra-strong. 

Double-Braid Stainless Flex

Others may only use flex bellows with a single-layer of braid, but Legendex stainless bellows are two-layers of stainless braid sandwiched together. 

800 Degrees Thermal Paint

The pipework and fittings have a thermal paint coating which is exhaust rated to 800 degrees Celsius (1470 Fahrenheit). This reduces heat transfer to the vehicle body and under-car equipment and adds another layer of corrosion resistance. The aluminised coating on some other brands begin to break down in temps over 600c – the aluminium begins to melt. This is never an issue with stainless.
