Parts for your 2012 Mitsubishi Outlander-Exhaust mount

2012 Mitsubishi Outlander Exhaust Mounts

Exhaust mounts (also called hanger insulators or exhaust rubbers) are absolutely used on the 2012 Mitsubishi Outlander. Technical sources including the Mitsubishi Outlander 2012 Workshop/Service Manual (Group 15 – Exhaust System), the Mitsubishi ASA/ASA2 parts catalogue for CW-series Outlander, and general repair guides such as the Haynes manual for 2007–2013 Outlander detail multiple rubber mounting points supporting the front pipe, centre section, and rear muffler. Aftermarket fitment catalogues from major exhaust suppliers also list replacement hanger rubbers specifically for the 2012 model, confirming their presence and serviceability.

On this Outlander, the exhaust mounts suspend the pipework and mufflers from the underbody while isolating vibration. They keep the hot exhaust tucked up and clear of the body, subframes and rear bumper, so nothing bangs, buzzes or melts. Because they’re rubber, they soak up engine and road vibrations that would otherwise end up in the cabin as annoying drones and rattles.

Over time, heat, road grime and the odd gravel track around Aus and NZ can harden or crack the rubbers. When they stretch or split, the tailpipe can sit crooked, knock over bumps or slap on start‑up. It’s smart to check the exhaust mounts at every routine service (roughly every 10,000–15,000 km), and sooner if there’s a rattle. In coastal areas where corrosion is a thing, keep an even closer eye on the hanger rods and brackets.

Replacement is straightforward with the right approach. Always work on a cold exhaust, support the system with a stand or jack, and give the old rubbers a spritz of silicone spray to slide them off the hanger pegs. Match the new insulators to the original size and angle, going too stiff (some polyurethane options) can add cabin noise. For AWD Outlander variants, there’s typically an extra mid/rear hanger to manage the longer system—make sure every mount is present and doing its bit. After fitting, check tailpipe alignment and clearances around the rear bumper, heat shields and crossmembers, and snug up any associated brackets. If the vehicle tows or sees rough roads, consider quality OE-spec rubbers rather than bargain-bin parts.

• Common signs it’s time: droopy or off-centre tailpipe, thuds over bumps, exhaust drone, visible cracks/perishing in the rubber, or contact marks on heat shields.
• Tip: Replace mounts in pairs or as a set if more than one looks tired—keeping tension even helps the system sit properly and prevents repeat visits.

Popular questions

How often should exhaust mounts be replaced on a 2012 Outlander?
There isn’t a fixed replacement interval. Have them inspected at each service, many last 5–10 years, but heat, towing, gravel roads and coastal corrosion can shorten that. Replace at the first signs of cracking, stretching or noise.

What are the symptoms of a failing exhaust mount?
Look and listen for a sagging or skew tailpipe, knocks over speed humps, new rattles at idle or on start-up, and visible splits in the rubber. If the exhaust touches a heat shield or bumper, you’ll often hear a buzz or thud.

Can aftermarket polyurethane hangers be used?
They can, and they’re tougher, but they often transmit more vibration. For daily driving and comfort, OE-style rubber is usually best. If you choose poly, match the size and angle carefully and expect a firmer feel.
