Parts for your 2013 Isuzu D-max-Exhaust mount

2013 Isuzu D‑MAX exhaust mount: what it does and how to look after it

Exhaust mounts (also called exhaust hangers or insulators) are used on the 2013 Isuzu D‑MAX. Factory documentation for the D‑MAX TFR/TFS platform (2012–2016) confirms the exhaust system is supported by multiple rubber insulator mounts along the front pipe, muffler and tail section. This is set out in the Isuzu D‑MAX 2012–2016 Workshop Manual under the Exhaust System section, and illustrated in the Isuzu Electronic Parts Catalogue (EPC) diagrams for the muffler/exhaust assemblies. Together, those technical sources verify the part is fitted and service‑relevant on the 2013 model.

On a 2013 D‑MAX, the exhaust mounts suspend the pipes, muffler and (where fitted) the DPF so the system can flex with engine movement and chassis twist without knocking on the body or driveline. They isolate vibration, keep heat and fumes where they should be, and help prevent cracked welds or broken brackets when the ute sees corrugations, towing or off‑road tracks.

These rubber insulators live a tough life: heat cycles, road grime, oil mist and UV all harden or crack them over time. As part of routine servicing, it’s smart to inspect each mount for splits, perishing, elongation of the holes, or metal-on-metal witness marks. A quick check every service or 10–15,000 km is plenty, and definitely after any exhaust work, suspension lift, big towing trip, or a WoF/roadworthy knockback.

• Common symptoms of tired mounts: exhaust thumps over bumps, new rattles or drone, tailpipe sitting crooked, or visible sag at the muffler.
• Handy fitting tips: let the exhaust cool, support it with a jack and wood block, replace mounts in pairs on the same section, and use a dab of silicone spray to slip new insulators on. Don’t preload the system—aim for even, relaxed support and adequate clearance to the crossmember, leaf springs, propshaft and bumper.

Quality matters. OEM‑grade rubber insulators keep NVH civil, firmer polyurethane hangers can be useful if the D‑MAX sees rough tracks or heavy towing, but may transmit a touch more vibration. If any bracket is bent or a weld cracked, sort that before tossing fresh mounts at it. With the right mounts in the right spots, the 4JJ engine’s shake stays out of the cab, the tailpipe sits true, and the exhaust lasts longer between repairs.

Replacement is straightforward with basic tools (spanners, pliers, penetrating oil). If the system is fighting you, or there’s a DPF and tight clearances, it’s worth a visit to a muffler shop.

FAQs

How many exhaust mounts does a 2013 D‑MAX have?
It varies with body style and exhaust layout. Expect several insulators spaced from the front pipe to the tail section. Longer wheelbase and 4x4 variants typically have an extra hanger or bracket to keep things stable.

What are the signs the mounts need replacing?
Look for rubber cracking or splitting, elongated holes, the muffler sitting low or skewed, fresh scrape marks where the exhaust has touched the chassis, and new knocks, rattles or droning—especially over bumps or at idle.

Should they be upgraded for towing or off‑road use?
Yes, sometimes. Good‑quality OEM‑spec rubber works for most utes. If the D‑MAX regularly tows heavy or sees corrugations, slightly firmer polyurethane hangers can reduce sag. Just note they can pass a bit more vibration into the cabin.
