2020 Mitsubishi ASX Exhaust Mount: Purpose, Care, and When to Replace

Yes, an exhaust-mount is fitted to the 2020 Mitsubishi ASX. Technical sources including the Mitsubishi Motors Workshop Manual for ASX/RVR (2019–2021), the ASA electronic parts catalogue, and OEM repair databases consistently show multiple exhaust mounting insulators (rubber hangers) supporting the front pipe, mid-section and rear muffler on this model. So it’s a relevant service item, not a delete or oddball part.

On the ASX, the exhaust-mounts are those tough rubber insulators that hold the exhaust in position while letting it move a little as the engine rocks and the pipework heats and cools. Their job is simple but critical: keep the exhaust centred, stop metal-on-metal contact, and soak up vibration so there’s less buzzing in the cabin. When they age, the rubber perishes and stretches, which can drop the tailpipe, twist the muffler, or cause knocks over bumps.

As part of regular servicing, it’s smart to eyeball the mounts every 10,000–15,000 km or at each service. Look for cracking, splits, hardening, or excessive sag. If the exhaust is sitting off-centre in the rear valance, or there’s a thud from the back end, chances are a mount has had it. Heat and road grime do them in over time, so five-to-ten years is a common lifespan depending on use and climate.

Replacement is straightforward with the car safely supported. Spray a little silicone lubricant on the pegs, then lever the old rubber off and slide the new one on. Always support the exhaust with a stand or jack to avoid stressing the joints. It’s good practice to replace mounts in pairs where they share a section, keeping everything even. Genuine or quality aftermarket rubbers both work, some uprated “stiffer” insulators can tame movement if there’s a towbar or bigger back box fitted, but don’t go too hard or you’ll transfer vibration into the cabin.

Signs it’s time to swap the exhaust-mounts:

• Rattles at idle or on cold start, quietening as things warm up
• Clunks over speed bumps or when backing off the throttle
• Tailpipe sitting low or skewed in the bumper cut-out
• Visible cracks, splits, or shiny rub marks on the exhaust

Keeping the ASX’s mounts fresh helps protect flex joints and welds, prevents annoying noises, and keeps the pipe exactly where Mitsubishi intended.

Popular questions about 2020 Mitsubishi ASX exhaust mounts

How many exhaust mounts are on a 2020 ASX?
Most 2020 ASX variants use several rubber hangers across the system — typically one near the front/mid section and a couple around the rear muffler. Exact count can vary slightly with trim and market spec, but there are multiple mounts supporting the pipework.

What symptoms point to a failed exhaust mount on an ASX?
Common giveaways include a droopy or off-centre tailpipe, rattles at idle, thumps over bumps, and new vibrations in the cabin. If a mount tears completely, the muffler can shift and tap the body or suspension.

Should exhaust mounts be replaced preventatively?
They’re inexpensive and easy to change, so replacing ageing, perished rubbers during a service or whenever the exhaust is off the car is a tidy bit of preventative maintenance. It reduces stress on joints and keeps things quiet.
