VEHICLE: Isuzu MU-X 3.0L TD Dec 2013+ 4JJ1TCX

 

Overview

This is Australia's toughest 3" stainless off-road exhaust system, in fact the only exhaust with an off-road warranty. Legendex delivers serious grunt & rumble. That means a more efficient engine for extended engine life, fuel economy and more power, especially when combined with a Legendex Optimizer Remap - and, of course, that commanding presence - that commanding sound that only Legendex delivers.

• Unrivalled 10 years off-road warranty
• 3" 409 (exhaust grade) stainless^
• High-flow stainless packed muffler
• Coated in 800 degree thermal paint
• Heavy duty hangers & brackets
• Ceramic coated dump pipe with 30% thicker tube
• High-flow diesel specific cat 

Legendary power gains

Paired with a Legendex Optimizer Remap, your Legendex exhaust will give you the maximum power gains… 

You’ll get at least 10% gains with just the exhaust mod - but we have seen 24% gains on the dyno and up to 40% when pairing the exhaust with a Legendex Optimizer Remap or PCM.

Easier, safer towing

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

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.
