Parts for your 2009 Mitsubishi Lancer-Exhaust mount

2009 Mitsubishi Lancer Exhaust Mount: purpose, service and replacement

Technical sources confirm the 2009 Mitsubishi Lancer is fitted with exhaust mounts (rubber exhaust hangers/insulators). The Mitsubishi Motors CJ Lancer workshop manual (exhaust system section) specifies exhaust hanger inspection and replacement, and the Mitsubishi ASA electronic parts catalogue lists multiple exhaust mounting insulators and brackets for the 2009 model. Major aftermarket catalogues used in AU/NZ parts counters also list direct-fit exhaust hanger rubbers for this Lancer. So yes—exhaust mounts are absolutely relevant to this vehicle.

On this Lancer, the exhaust mounts suspend the exhaust system from the underbody while isolating vibration. They keep the pipework and muffler correctly positioned, protect the flex joint and flanges from stress, and stop the tailpipe from knocking the bumper or underbody. Because they live near heat and road grime, the rubber slowly hardens, cracks, or stretches. When that happens, the exhaust can sit low, rattle over bumps, or clunk on start-up or shutdown—classic signs the mounts are due.

As part of routine servicing in Australia and New Zealand, it’s sensible to inspect the mounts every 10,000–15,000 kilometres or at each service. A quick look on a hoist will usually do it. Any perished, torn, oil-soaked, or badly stretched hanger should be replaced. Keeping mounts healthy helps the Lancer pass roadworthy/WOF checks and prevents costly damage to the flex pipe, catalytic converter, or rear muffler.

• Common symptoms: exhaust sagging, thumps over speed bumps, tip touching the bumper, buzz or vibration at idle, metallic rattle on rough roads.
• Quick checks: look for cracks in the rubber, shiny witness marks where the exhaust has been touching, and loose or rusty brackets.
• Good practice: replace mounts in pairs at the rear, and re-centre the exhaust in the bumper cut-out after fitting.

Replacement is straightforward: support the exhaust with a jack stand, mist the old rubbers with silicone spray, lever them off the pegs, fit the new hangers, then check alignment. Tighten any bracket fasteners to the values in the Lancer service manual and ensure adequate clearance to the subframe, heat shields, and bumper. Always work on a cool exhaust and use stands, not just a jack.

For parts choice, quality OEM-style rubber hangers are quiet and durable for daily use. Polyurethane hangers can add support on lowered cars but may increase cabin NVH a touch. A fresh set of mounts keeps the 2009 Lancer tidy, quiet, and compliant on Aussie and Kiwi roads.

• How many exhaust mounts does a 2009 Lancer have?
  Most non-turbo 2009 Lancers use around three to five hangers, depending on body style and market: usually one near the front pipe support, one around the centre/resonator area, and two at the rear muffler. Variants with different exhaust layouts may use an extra bracket or insulator.
• What are the signs the mounts need replacing?
  Look for a drooping tailpipe, knocks over driveway entries, buzzing at idle, or the tip melting or marking the bumper. Underneath, perished or cracked rubber, elongated holes, or torn hangers are clear replacement cues.
• Are polyurethane hangers a good idea on a daily-driven Lancer?
  They can help keep alignment on lowered or spiritedly driven cars, but they may transmit a bit more vibration into the cabin. For a quiet commuter, quality rubber is usually the best balance.
