Parts for your 2009 Mitsubishi Outlander-Exhaust mount

2009 Mitsubishi Outlander Exhaust Mount

Exhaust mounts (also called exhaust hangers or insulators) are absolutely used on the 2009 Mitsubishi Outlander. Technical sources including the Mitsubishi Outlander 2007–2010 Service Manual (Group 17: Exhaust System), the Mitsubishi ASA electronic parts catalogue for CW-series Outlander, and common aftermarket catalogues from exhaust suppliers list multiple rubber exhaust hanger insulators and brackets supporting the front pipe, centre section, and rear muffler on this model. That means the exhaust-mount is relevant, fitted, and serviceable on a 2009 Outlander.

On the Outlander, the exhaust mounts are tough rubber insulators that suspend the exhaust under the vehicle while allowing a bit of movement. They soak up vibration, keep the pipework aligned, and stop the muffler from knocking the body. Over time, heat, road grime, and age can harden or crack the rubber, leading to rattles, thumps over bumps, or a tailpipe that doesn’t sit straight. Left too long, a failed mount can stress welds, cause premature joint leaks, or let the system contact underbody components.

As part of routine servicing, it’s smart to eyeball the mounts every 10,000–20,000 kilometres or at each oil change—especially if the Outlander sees gravel roads, towing, or lots of short trips. Look for perished rubber, splits, stretched holes, or metal hangers that are chewing into the rubber. Check all mounting points: near the front pipe, mid hanger(s), and at the rear muffler.

• Common signs it’s time to replace: exhaust rattles or clunks, a sagging or skewed tailpipe, vibration in the cabin at idle, or visible cracks in the rubber.
• Handy tip: a quick spray of silicone lube helps slide the old insulators off and the new ones on.

Replacement is straightforward for a competent DIYer, but a hoist makes life easier. Support the exhaust with a stand, remove the old rubber insulators, inspect the metal hangers and brackets for rust or bends, then fit quality replacements in the same orientation. If any bracket bolts are removed, tighten them to the manufacturer’s spec. After fitting, ensure there’s clearance around heat shields, crossmembers, and the rear bumper. A short test drive over a few bumps will confirm quiet operation.

Quality aftermarket or genuine rubber mounts are inexpensive and can save bigger exhaust repairs down the track. For Outlanders with more kilometres or in coastal areas, consider proactive replacement in pairs to keep the system level and calm.

• How many exhaust mounts does a 2009 Outlander have?
  Most 2009 Outlanders use three to five mounts, depending on engine, drivetrain (2WD vs AWD), and exhaust layout. Expect one near the front/centre section and multiple supports around the rear muffler to keep it stable.
• Is it safe to drive with a broken exhaust mount?
  It’s not ideal. A broken or missing mount can let the exhaust sag and bang on the body, risk cracking joints, or strain the flex section. Short trips to a workshop are usually fine if the system is still supported, but fix it promptly.
• What does an exhaust mount replacement cost?
  The rubber insulators are inexpensive, and labour is typically minimal if bolts aren’t seized. Many workshops can replace one or two mounts during a standard service visit at modest cost.
