Parts for your 2020 Mitsubishi Eclipse cross-Exhaust mount

2020 Mitsubishi Eclipse Cross exhaust-mount: purpose, checks and replacement

Based on Mitsubishi technical documentation, exhaust-mounts (rubber insulators/hangers) are absolutely fitted to the 2020 Mitsubishi Eclipse Cross and are relevant service items. The Mitsubishi Motors Service Manual for Eclipse Cross (GK/GL, 2018–2020), Group 15 – Exhaust System, details the exhaust supports, and the Mitsubishi ASA Electronic Parts Catalogue shows multiple exhaust insulators supporting the centre pipe and rear muffler. So this model does use exhaust-mounts.

The exhaust-mount’s job is simple but crucial: hold the exhaust system in the right position while isolating vibration and harshness from the cabin. On the 2020 Eclipse Cross, a series of rubber hangers lets the system move slightly as the engine rocks and the pipework heats and cools. That flex protects the manifold and flex joint, prevents metal-on-metal contact, and keeps the tailpipe clear of the bumper.

Over time, heat, road grime, and age can harden or crack the rubber. When the mounts tire out, owners might notice a dull thud on start-up or shutdown, a rattle over corrugations, or the muffler sitting lower than usual. Left too long, a sagging system can stress welds and joints, or knock on the subframe.

• Inspection timing: have the mounts checked at each routine service or every 20,000 km, and after any underbody knock or off‑road excursion.
• What to look for: perishing, splits, elongation of the holes, shiny witness marks where the exhaust has contacted the body, and uneven muffler height.
• Replacement tips: use quality OE‑spec insulators, replace any mount that’s cracked, overly soft, or stretched, and re-check exhaust alignment and clearances after fitting.
• Fitting notes: a dab of silicone spray helps removal/refit, avoid petroleum grease on rubber. Always work on a cool exhaust and support the system so the flex joint isn’t strained. Torque values and bracket positions should follow the Mitsubishi workshop manual.

Owners upgrading to an aftermarket exhaust should ensure the new system retains the factory hanger locations, or uses properly engineered brackets. Mixing old, heat-soaked mounts with a new system can create rattles—swapping them as a set is cheap insurance against come-backs. With fresh mounts, the Eclipse Cross stays quiet, properly aligned, and happier over Aussie and Kiwi roads.

Popular questions

How often should exhaust-mounts be replaced on a 2020 Eclipse Cross?
There’s no fixed age, because heat and driving conditions vary. Most workshops inspect at each service and replace on condition. In hotter climates or with frequent short trips, mounts may age faster, expect inspection by 60,000–80,000 km to catch early perishing.

What are the common symptoms of failing exhaust-mounts?
Tell‑tales include a sagging muffler, new rattles over bumps, thuds when starting or stopping the engine, and the tailpipe shifting in the bumper cut-out. Any fresh exhaust smell or noise should prompt an immediate underbody check.

Can an aftermarket exhaust change the number or style of mounts?
Yes. Some performance systems relocate or add hangers. That’s fine if brackets line up with factory points and the rubber insulators are suitably heat- and load-rated. Always confirm clearance to the body, towbar, and heat shields after installation.
