2005 Mitsubishi Lancer Exhaust Mount: What It Does and When to Replace It

Exhaust mounts (also called exhaust hangers or insulators) are absolutely used on the 2005 Mitsubishi Lancer. Mitsubishi’s CS/CH Lancer Service Manual (2001–2007, Exhaust System section) specifies rubber insulators supporting the front pipe, centre section and rear muffler. This is backed by OEM parts catalogues (Mitsubishi ASA/CAPS) and common aftermarket catalogues used in Australia and New Zealand, which list multiple exhaust hanger insulators for the 2005 Lancer. So yes—this part is relevant on the model.

On a 2005 Mitsubishi Lancer, the exhaust mount’s job is simple but vital: hold the exhaust in the right position while soaking up vibration so the cabin stays quiet and the system doesn’t bash into the floor, subframe or suspension. Good mounts keep stress off the manifold, flex joint and welds, and maintain proper clearance around heat shields and the rear bumper.

Because they’re rubber, mounts harden, crack or stretch over time—especially with heat, road grime and the odd speed hump hit. As part of routine servicing, they’re worth a quick look whenever the car is on a hoist for an oil change or tyre rotation.

• Tell-tale signs it’s time: a thunk or rattle over bumps, a droopy tailpipe, more vibration at idle, or fresh contact marks on the exhaust or underbody.
• Inspection habit: check at 10,000–15,000 km intervals or annually, look for splits, perishing, elongation of the holes, or shiny rub points near brackets.
• Replacement tips: support the exhaust with a stand or jack, spritz the pegs with silicone spray, and lever the old rubbers off. Fit new insulators with the correct orientation and confirm clearances all around before lowering the car.

Owners can choose OEM-style rubber (quiet and comfy) or firmer polyurethane (longer lasting but may pass a bit more vibration). If one mount has failed, checking and often replacing the neighbouring ones is smart—age and heat affect them as a set. Brackets and bolts that hold the pegs should also be checked for corrosion, tighten to the service manual guidance.

The job is quick—often 15–45 minutes per mount—and pays off by protecting the rest of the exhaust system, keeping the Lancer sounding tidy and preventing nuisance knocks that can masquerade as suspension trouble.

Popular questions about 2005 Mitsubishi Lancer exhaust mounts

Where are the exhaust mounts located on a 2005 Lancer?
The Lancer typically has rubber mounts at the rear muffler, near the centre resonator/pipe, and sometimes closer to the front pipe. They hook over metal pegs on the exhaust and body brackets to suspend the system evenly.

What symptoms point to worn exhaust mounts on a 2005 Lancer?
Common clues include a rattle or thud over bumps, a sagging or off-centre tailpipe, extra vibration at idle, or a buzzing noise where the exhaust kisses a heat shield. Visual cracks or stretched holes in the rubber are a giveaway.

Should polyurethane hangers be used on a daily-driven Lancer?
Poly hangers are durable and great for hard driving, but they can transmit more vibration. For daily use, quality OEM-style rubber usually gives the best comfort and noise isolation, poly can suit cars with upgraded exhausts that need firmer support.
