Parts for your 2010 Mitsubishi Lancer-Exhaust mount

2010 Mitsubishi Lancer exhaust mount

Exhaust mounts (also called exhaust hangers or insulators) are definitely used on the 2010 Mitsubishi Lancer. This is documented in Mitsubishi’s factory Service Manual for the Lancer CJ/CF (Group 15 – Exhaust System), which details removal/installation of the exhaust “support insulators,” and in the Mitsubishi ASA electronic parts catalogue for CY4A/CX4A/CZ4A models, which lists multiple “insulator, muffler/exhaust” positions along the system. General repair texts for the 2007–2015 Lancer range also reference these rubber insulators as standard fitment. So an exhaust mount is very much relevant to a 2010 Lancer.

The exhaust mounts on a 2010 Lancer suspend the front pipe, centre section and rear muffler from the body, keeping the system located while isolating vibration and exhaust movement from the cabin. They’re rubber insulators that allow a controlled amount of flex so the system can move under load, over bumps and with heat expansion, without knocking on the subframe, heat shields or bumper. On CJ/CF Lancers there are typically several mounts from front to rear, and they’re considered serviceable wear items.

As part of routine servicing, those mounts deserve a quick inspection. Heat, age, road grime and oil contamination harden or crack the rubber, and elongated holes let the exhaust sag. Owners may notice dull thumps over speed humps, a tinny rattle at idle, or a tailpipe that sits off-centre, all point to tired mounts. If the exhaust has been replaced with a heavier aftermarket muffler, the extra weight can accelerate mount wear, especially on vehicles that see corrugated roads around regional Australia or coastal environments in NZ.

Replacement is straightforward for a workshop: support the exhaust, then swap insulators one at a time to avoid stressing joints. A spritz of silicone spray helps slide new rubbers on. It’s wise to check the metal hanger rods for rust or bent alignment and confirm all brackets and heat shields are tight to spec from the Mitsubishi manual. Quality OEM-spec rubber insulators restore factory NVH, while firmer polyurethane versions add support for performance systems but can transmit more vibration into the cabin.

There’s no fixed kilometre-based interval, but a visual check at every service and proactive replacement around the 80,000–120,000 km mark keeps the Lancer’s exhaust quiet and correctly aligned. Genuine or equivalent high-grade aftermarket mounts are recommended to handle heat and UV in Aussie and Kiwi conditions.

• Common signs of worn mounts: rattles/knocks, sagging tailpipe, melted bumper trim, exhaust contacting crossmembers.
• Service tip: replace mounts in pairs/groups if one has failed, and recheck clearances with the vehicle at ride height.

How many exhaust mounts does a 2010 Lancer have?

Most CJ/CF Lancers run several insulators from the front pipe to the rear muffler, typically three to five depending on body style and engine. Variants with different mufflers or Sportback trims may use an extra insulator at the rear.

Are polyurethane exhaust mounts a good idea on a Lancer?

They can be, especially for heavier aftermarket exhausts, as they resist heat and stretch. The trade-off is a bit more vibration transmitted into the cabin compared with OEM-style rubber.

What makes exhaust mounts fail early?

Heat cycles, oil or fluid contamination, coastal corrosion, misaligned exhaust hardware and heavy mufflers all shorten mount life. Regular inspections and prompt replacement keep the system secure and rattle-free.
