Grunt is worth a thousand words

…ask any bloke. When your 4wd responds to every nuance of the throttle, pushing you back in your seat, that’s grunt. It doesn’t lag and it doesn’t wallow like a fat man in the bathtub. Grunt drives like ACDC on the Highway to Hell and the turbo wants to sing like a banshee.

D40 V6 3L PCM exhaust s

Dyno shows a Nissan Navara D40 3L V6 TD with a stock exhaust (blue) versus a Legendex exhaust and PCM (red) for a 28% max HP gain at 70 kmh – stock peak of 150.3 HP is achieved around 100 kmh (not shown on the chart) – and the torque gains are huge in the everyday driving range 60-80 kph.

Listen to the Rumble

Women love it and blokes want to sound like it. Rumble turns heads and makes Legendex distinct from the rest. It’s not harsh and it doesn’t drone when you’re towing. Rumble is that subtle note of menace that we secretly love. Rumble defines the warrior before his battle fury is unleashed.


This is Australia’s toughest 3″ stainless off-road exhaust system, in fact the only Navara D40 exhaust with an off-road warranty. Legendex delivers serious grunt & rumble. That means much more power, engine life and economy – and that commanding presence, that distinct sound that only Legendex delivers.

Up to 40% power gains

Paired with a Legendex PCM your Legendex exhaust will give you the maximum power gains. You are guaranteed at least 10% gains with just the exhaust mod – but we have seen 24% gains on the dyno and up to 40% with both exhaust and PCM mods

Easier, safer towing

The extra power takes the stress out of towing. Hill climbs are easy. Safe, quick overtaking is back on the table. That extra power means safer manouvering.

Better fuel economy

Because your engine is more efficient it uses less fuel – typically 8-12% fuel savings. It won’t be long before your investment pays for itself.

Easy DIY fit

We test fit every Legendex exhaust system on our backs in the dirt. No hoist or jacks are required. No cutting or welding. No special mechanical skills or tools are required. We only use the factory mount points and WE GUARANTEE A PERFECT FIT – OR YOUR MONEY BACK!

*No Cat configuration option: Available for designated off-road use, track use and agricultural exemptions. We recommend fitting a catalytic converter. The benefits outweigh the minimal disadvantages. The advantages include: prevention of turbo over-spooling by clever design on our part, clean emissions, legal on-road compliance (required where the vehicle was originally fitted with a cat).  Because we use a high-flow cat, the effect on engine performance is insignificant – less than 2% difference as measured on a dyno.
