Parts for your 2018 Mitsubishi Outlander-Exhaust mount

2018 Mitsubishi Outlander exhaust-mount: purpose, care, and when to replace

Exhaust mounts are absolutely fitted to the 2018 Mitsubishi Outlander. Technical references including the Mitsubishi Motors Service Manual for the GF/GG Outlander platform (Exhaust System section) and the Mitsubishi ASA/CAPS parts catalogue list multiple rubber exhaust hangers/insulators and their brackets along the front pipe, centre section, and rear muffler. These mounts are standard hardware on production vehicles to support the exhaust and isolate vibration.

On the Outlander, the exhaust-mounts (often called hangers or insulators) suspend the exhaust so it sits at the right height and clears heat shields, the rear bumper, suspension arms, and the underbody. Their rubber construction soaks up engine and road vibration, keeping drone and rattles out of the cabin. They also allow a little controlled movement so thermal expansion doesn’t stress the pipework or flanges.

As part of regular servicing, the mounts deserve a quick look. Rubber ages with heat, road grime, and oil contamination, so a 2018 vehicle can start to show perishing or softening. A practical check every 10,000–20,000 km (or at each scheduled service) works well: if the rubber is cracked, elongated, oil-soaked, or the exhaust sits off-centre, it’s time to replace. Using OE-grade or high-temp EPDM mounts that match the original shape helps the system sit correctly and prevents new knocks.

Replacement is straightforward for a workshop. The car is safely raised, the exhaust allowed to cool, and the old insulators eased off their pegs (a dab of silicone spray helps). Brackets and fasteners are inspected and tightened to the workshop manual spec after the new mounts are on. Because the rear muffler usually hangs on two mounts, replacing them as a pair helps keep the muffler level. If a knock persists after fitting, the technician will re-check clearances and alignment.

• Common symptoms of tired mounts: thumps over bumps, metallic rattles at idle, exhaust tip sitting low or skewed, or visible cracking/sagging of the rubber.
• Service tips: keep oil and solvents off the rubber, use silicone spray (not petroleum grease) for install, and inspect nearby heat shields while there.

Look after the mounts and the Outlander’s exhaust stays quiet, secure, and compliant with roadworthy/WOF expectations across Australia and New Zealand.

FAQs: 2018 Mitsubishi Outlander exhaust-mount

How many exhaust mounts does a 2018 Outlander have?
Depending on engine and drivetrain, most 2018 Outlanders use around four to six rubber hangers: typically one near the front pipe/flex area, one or two on the centre section, and two at the rear muffler. The exact count can vary with AWD vs 2WD and trim.

What are the signs the exhaust mounts need replacing?
Owners often notice a dull knock over speed humps, a rattle at start-up or idle, or the tailpipe sitting lower or off-centre in the bumper cut-out. A quick under-car look may show cracked or stretched rubber, or a hanger that has popped off its peg.

Can universal hangers be used, or should they be OEM?
Quality universal hangers can work in a pinch, but matching the OE shape, length, and rubber durometer is important to keep the exhaust aligned and quiet. For the Outlander, OEM or direct-fit aftermarket hangers are usually the safest bet.
