Parts for your 2012 Mitsubishi Lancer-Exhaust mount

2012 Mitsubishi Lancer Exhaust Mount — What it does and when to replace it

Yes, the 2012 Mitsubishi Lancer uses exhaust mounts (also called exhaust hangers or insulators). This isn’t a niche part — it’s standard kit. Technical sources such as the Mitsubishi Lancer 2007–2017 (CJ/CY/CZ) workshop manual (Group 15: Exhaust) and the Mitsubishi ASA electronic parts catalogue list multiple rubber exhaust mounting insulators along the system, and general repair guides like the Haynes manual for the same generation describe removal/refit via these rubber mounts. So an exhaust-mount is absolutely relevant and used on this model.

On the 2012 Lancer, the exhaust mounts are tough rubber insulators that hold the exhaust in place while soaking up vibration. They keep the muffler and pipes sitting where they should — clear of the subframe, heat shields, and bumper — while letting the system move a touch as the engine rocks and the car flexes. Without healthy mounts, the exhaust sags, knocks, and can stress the welds or flange joints.

During regular servicing, it pays to give each mount a quick once-over. There are several along the system, typically around the rear muffler and mid-pipe. If the car is a Sportback, Ralliart, or Evo X, the count and positions differ slightly, but the job of each mount is the same. Look for cracking, hardening, splits, or elongated holes. If the muffler looks crooked, sits low, or the tailpipe is no longer centred in the bumper cut-out, suspect a tired mount.

• Common signs a mount needs replacing: thumps over bumps, rattles on take-off, buzzing at idle, or the exhaust tapping a heat shield.
• Quick tip: a light spray of silicone makes removing old rubber insulators much easier. Support the exhaust with a jack stand before unhooking anything.

Replacement is straightforward for a home mechanic with stands and basic hand tools. Unhook the old insulators, inspect the metal pegs and brackets for rust or loose hardware, and refit new quality rubber (polyurethane hangers are an option but can add a bit of cabin buzz). After installation, adjust for clearance all round — aim for a healthy gap to the body and shields — then snug the bracket hardware to the factory spec from the workshop manual and take a short test drive to check for knocks.

Swapping mounts in pairs or as a small set helps keep the system sitting even, and it’s a low-cost way to stop annoying noises and protect the rest of the exhaust on a 2012 Lancer.

Popular questions

How many exhaust mounts are on a 2012 Mitsubishi Lancer?
It varies by trim and body style, but most non-turbo sedans run about three to five rubber mounts spread from the mid-pipe to the rear muffler. Ralliart and Evo X setups can have additional mounting points to suit their different pipework and mufflers.

What are the symptoms of a failing exhaust mount?
Look for a droopy or off-centre tailpipe, clunks over bumps, rattles at idle, or a metallic tap when taking off. You might also notice the exhaust touching a heat shield or the bumper when parked on uneven ground.

Can the mounts be replaced at home?
Yes, provided the exhaust is cool and the car is safely supported. A spray lubricant, pliers, and a pry bar usually do the trick. Support the exhaust before removing the old rubbers, and double-check clearances after fitting the new ones.
