Parts for your 2015 Mitsubishi Asx-Exhaust mount

2015 Mitsubishi ASX exhaust-mount (hanger) — what it does and when to replace it

Technical sources confirm the 2015 Mitsubishi ASX uses exhaust mounts (also called exhaust hangers or insulators). The Mitsubishi Motors workshop manual for RVR/ASX (Group 15 – Exhaust) illustrates rubber muffler hangers supporting the centre and rear sections, and the Mitsubishi ASA electronic parts catalogue lists multiple “insulator, muffler mounting” positions for ASX model years around 2010–2016. Major aftermarket catalogues also offer direct-fit hanger rubbers for the 2015 ASX, reinforcing that these mounts are a standard, serviceable part on the vehicle.

On this ASX, exhaust mounts are the tough little rubber isolators that hold the exhaust in place while soaking up vibration. They keep the pipes and mufflers sitting at the right height, stop the system knocking on the body or subframes, and allow a bit of movement as everything heats up and cools down. Without them, you’d have rattles, stress cracks, and a tailpipe that doesn’t stay where it should.

Because they live under the car, these mounts cop heat, road grime, and the odd splash of oil, so they can harden, crack or tear over time. A quick look during regular servicing goes a long way. Most owners will get many years out of them, but climate, short trips, and rough roads can speed up wear.

• Common tell-tales of tired mounts: a droopy tailpipe, thuds over bumps, a metallic rattle at idle, or the exhaust touching a crossmember or heat shield.
• Inspection tips: with the ASX safely raised, check each rubber for splits, elongation, glazing/hardening, or missing hangers. Make sure brackets and welds aren’t cracked.
• Replacement advice: support the exhaust, then pop the old rubber off the pegs. A spritz of silicone spray or soapy water helps. Fit quality OEM or equivalent rubbers and confirm the exhaust clears heat shields, bumper, and suspension through its full movement.

Good practice is to replace any suspect hangers as a set on that section (for example, both rear muffler mounts) so the exhaust sits evenly. If a mount has failed, give the rest of the system a once-over—failed hangers can load up flex joints and flanges. After fitting, start the ASX and check for knocks and leaks. It’s a simple, affordable bit of maintenance that keeps the cabin quiet and the system happy for many more kilometres.

How often should exhaust mounts be replaced on a 2015 Mitsubishi ASX?

There’s no fixed interval, they’re replaced on condition. During routine services, a visual check is usually enough. Many ASX owners won’t need them until well past 80–120,000 kilometres, but harsh conditions or lots of short urban trips can age the rubber faster. If you hear knocks or see the tailpipe sitting off-centre, move replacement up the list.

What are the signs of a failing exhaust mount on the ASX?

Look for a sagging tailpipe, new rattles or thuds over bumps, or the exhaust touching a heat shield. You might also notice more vibration in the cabin at idle. Underneath, the rubber can look cracked, stretched, or perished. If in doubt, gently lift the exhaust by hand—excessive movement usually points to a tired hanger.

Is it safe to drive with a broken exhaust mount?

It might get you home, but it’s not ideal. A missing or torn mount can let the exhaust knock on the body, damage flex joints, or stress other mounts. If the system sags, it could also affect clearances on speed humps or driveways. Best bet: avoid long trips, keep speeds down, and book a repair promptly.
