Manta 3in Exhaust - Isuzu MU-X 3.0L Turbo Diesel 2013-2025

Manta 3in mandrel-bent exhaust for the Isuzu MU-X 3.0L turbo diesel. Australian made. Three choices and you are done.

The factory MU-X exhaust is the biggest thing holding the 4JJ back. Going to a free-flowing 3in system brings the turbo on boost noticeably earlier, lifts torque through the mid range, and drops exhaust gas temperatures.

1. Pick your MU-X

• Jan 2017 - Jun 2021 (MY19) - fitted with a DPF
• Jul 2021 - 2025 (MY21) - the facelift, also fitted with a DPF
• Nov 2013 - Jan 2017 - the original MU-X, no DPF

The two DPF cars take a different DPF Back section, so check your build date if you are close to mid 2021.

2. Pick your system

• DPF Back - replaces the exhaust from the DPF back and keeps the factory DPF in place. Road legal, no tune needed, and the cheapest way into a 3in system. DPF cars only.
• Turbo Back, With Cat - the whole exhaust from the turbo back, retaining a catalytic converter.
• Turbo Back, No Cat - the whole exhaust from the turbo back with a cat delete pipe. The most free-flowing option.

Read this before choosing a turbo back system. On the 2017-onwards cars a turbo back replaces the factory DPF and needs an ECU recalibration to suit. Manta supplies turbo back systems for off-road and race use only, and a cat or DPF delete is not legal for road use in Australia. If your MU-X is a road-registered daily, the DPF Back system is the one you want. Talk to us about tuning if you are going turbo back.

3. Pick your sound and material

Quiet runs a full rear muffler and stays close to factory in-cabin noise. Medium runs a hotdog resonator for a deeper note without highway drone. Loud is straight through with no muffler - the most aggressive, with plenty of turbo whistle.

Aluminised Steel is Manta's mild steel with an aluminised coating - best value, 2 year warranty. Stainless Steel is 409 grade with a 10 year warranty, and worth it if you see coastal air, beach sand, heavy mud or river crossings.

What you gain

• Turbo boost comes on earlier, so it feels far more responsive down low
• More torque through the mid range - better for towing and hills
• Lower exhaust gas temperatures
• Improved fuel consumption

Every option is a complete bolt-on kit - clamps, gaskets and hangers included, using the factory mounting points. The DPF Back option only exists for the DPF cars, so pick your MU-X first and the rest will filter down.
