Parts for your 2020 Mitsubishi Outlander-Exhaust mount

2020 Mitsubishi Outlander exhaust-mount: purpose, fitment, and upkeep

Exhaust-mounts are absolutely fitted to the 2020 Mitsubishi Outlander. Technical sources including the Mitsubishi Motors Outlander Workshop Manual (MY2020, Exhaust System section) and the Mitsubishi ASA electronic parts catalogue depict multiple rubber exhaust mounting insulators (“exhaust hangers”) supporting the front pipe, centre section and rear muffler. Mainstream parts catalogues used by workshops in AU/NZ also list direct-fit exhaust hanger rubbers for 2015–2021 Outlander models, confirming real-world fitment across petrol and PHEV variants.

On the Outlander, the exhaust-mount’s job is to suspend the exhaust and isolate vibration so cabin comfort stays tidy and the system sits at the correct height and angle. The rubber insulators absorb engine movement and road shock, protecting joints, flex sections and catalytic components. When mounts age, harden or tear, the exhaust can sag or go off-centre, which can stress flanges, cause rattles against shields or the rear crossmember, and transmit vibration into the cabin.

There’s no fixed replacement interval in the workshop manual, instead, inspection is recommended during routine servicing, particularly on vehicles that see gravel roads, tow regularly, or live in coastal areas where rubber and metal hardware cop corrosion. Technicians look for perishing, cracks, elongation of the rubber holes, and bent or rusty mounting pins and brackets. Any evidence of contact marks on the exhaust or shields is another giveaway.

When replacement is needed, supporting the exhaust with a stand, applying a silicone-safe lubricant, and swapping one hanger at a time keeps alignment true. Using OE-spec or quality aftermarket rubbers with the correct durometer helps maintain the Outlander’s intended NVH balance. Bracket fasteners should be tightened to the service manual’s torque guidance, and tailpipe alignment checked relative to the bumper cut-out. On PHEV models, note the slightly different rear section routing, mount locations remain, but clearances should be verified after refit.

• Common symptoms owners notice:
  • Rattling or thumping over bumps
  • Exhaust sitting low or skewed in the bumper
  • New vibration or droning at idle
• Service tip: replacing mounts in pairs on the affected section helps restore even support and reduces repeat visits.

Popular questions about 2020 Mitsubishi Outlander exhaust-mount

How many exhaust-mounts does a 2020 Outlander typically use?
Most 2020 Outlanders use several rubber hangers across the system—commonly at the front pipe/centre, mid-muffler area, and rear muffler. Exact count can vary slightly with engine/trim (petrol vs PHEV) and market, but technicians will generally see three to five insulators along the length.

Is there a set service interval for exhaust-mount replacement?
No set kilometre interval is specified. Workshops check them during routine servicing. In harsher use—towing, rough roads, coastal environments—they can age faster. If cracks, hardening, elongation, or sagging are present, replacement is advised straight away.

Can universal exhaust hangers be used on the Outlander?
Universal rubbers can work in a pinch, but the best results come from OE or direct-fit aftermarket mounts matched for hole spacing and rubber hardness. Correct fit helps keep the tailpipe centred and maintains factory ride comfort and noise levels.
