Parts for your 2015 Nissan Pulsar-Exhaust mount

2015 Nissan Pulsar (C12) exhaust mounts — what they do and when to replace them

Exhaust mounts are absolutely used on the 2015 Nissan Pulsar (C12). Technical references that confirm this include the Nissan Pulsar C12 Service Manual (Exhaust System section), which illustrates the muffler/centre pipe supported by rubber “insulator” mounts, and OEM/aftermarket parts catalogues for the C12 that list exhaust mounting rubbers for the rear muffler and mid-pipe. These sources make it clear the Pulsar relies on rubber exhaust mounts to suspend and isolate the exhaust system.

On the 2015 Pulsar, exhaust mounts (also called exhaust hanger rubbers or insulators) keep the exhaust where it should be while soaking up vibration. They let the system move a touch under load and heat expansion, preventing stress at the manifold and flex joint, and helping the muffler sit straight under the bumper. When they perish, the owner often notices knocks over bumps, a droopy muffler, a rattly idle, or the tip sitting off-centre in the rear valance.

As part of servicing, it’s smart to inspect the mounts whenever the car is on a hoist—oil changes, brake jobs, WOF/rego checks—because heat, road grime, and age harden and crack the rubber. Replacement is a quick job for a workshop and very doable at home with stands.

• When to replace: visible cracks or splits, elongated holes, excessive sag, contact marks where the exhaust taps the body, new droning or thuds.
• Maintenance tips: give the mounts a quick spray with silicone to reduce squeaks, keep oil and degreasers off them, check adjacent brackets for corrosion or loose fasteners.

If a mount is tired, support the exhaust with a jack and wood block, then lever the old rubber off the pegs. A dab of silicone spray helps slide the new one on. Choose quality, vehicle-specific rubbers (the Pulsar usually has one mid-pipe and one or two at the rear muffler, depending on body style). Universal mounts can work in a pinch, but the hole spacing and thickness need to match so the system doesn’t sit skew-whiff. Tighten any bracket bolts to factory spec per the Nissan service manual and make sure the tip clears the bumper evenly.

With fresh mounts, the Pulsar’s exhaust sits where it should, vibrations drop, and the rest of the system lasts longer.

Popular questions about 2015 Nissan Pulsar exhaust mounts

How many exhaust mounts does a 2015 Pulsar have?
Most C12 Pulsars run a mid-pipe mount plus one or two rear muffler mounts, depending on hatch or sedan and trim. A quick visual under the car will confirm the exact count and style.

Can universal exhaust mounts be used?
They can, but it’s best to match the Pulsar’s hanger rod diameter, spacing, and thickness. Too stiff (e.g., some polyurethane) can transmit vibration, too soft lets the muffler sag or knock.

What does replacement usually cost?
In Australia and NZ, quality rubbers are typically $15–$40 each, with 0.3–1.0 hour labour depending on access and rust. Many owners see a fitted price around $100–$200 for a pair at a workshop.
