Parts for your 2017 Nissan Pulsar-Exhaust mount

2017 Nissan Pulsar exhaust-mount — purpose, care and when to replace

Yes, the 2017 Nissan Pulsar uses exhaust mounts. Nissan’s factory service information for the B17/C12 Pulsar/Sylphy/Sentra platform (EX – Exhaust System section) specifies multiple rubber exhaust mounting insulators/hangers supporting the front pipe, centre section and rear muffler. Nissan’s FAST parts catalogue for the same platform also lists “insulator – rubber, exhaust” at those positions. So an exhaust-mount is absolutely relevant on this vehicle.

On a 2017 Pulsar, the exhaust mounts (often called rubber hangers or insulators) do the quiet work of holding the exhaust in place while soaking up vibration. They let the system move a touch as the engine rocks and the pipework heats and cools, stopping knocks, rattles and droning in the cabin. They also keep the tailpipe sitting neatly in the bumper cut-out and protect the flex joint and oxygen sensor wiring from undue stress.

There’s no fixed replacement interval, but these rubber bits harden, crack or stretch with age, heat and road grime. A quick look every service (around 10,000–15,000 km) is smart, and more often if the car sees gravel roads, towing or lots of short trips. If any mount is perished, split, oil-soaked or the muffler looks a bit droopy, it’s time to swap them.

• Common symptoms: thuds over bumps, a tinny rattle at idle, sagging tailpipe, new exhaust drone, or visible cracks in the rubber.
• Typical locations: one at the front/centre pipe, one on the resonator, and one or two at the rear muffler.

Replacement is straightforward with the right approach. Support the exhaust with a stand or jack, spray a little silicone lubricant on the hangers, and slide the rubber off the hooks. Fit like-for-like quality rubber or OE-spec mounts, overly stiff universal hangers can transmit vibration into the cabin. If one mount has failed, consider doing the set so the system sits level. After refit, check tailpipe alignment, clearance to the bumper and suspension, and that no heat shields buzz at idle.

Tech tip: while you’re there, eyeball the metal hanger rods and brackets for rust or cracks, and make sure the flex pipe and O2 sensor wiring aren’t under tension. Keeping the mounts healthy helps the Pulsar feel refined and prevents expensive strain elsewhere in the exhaust.

Popular questions about 2017 Nissan Pulsar exhaust-mount

How many exhaust mounts does a 2017 Pulsar have?
Most Pulsars run three to five mounts depending on hatch or sedan and exact exhaust layout. You’ll typically see one up front, one mid-pipe, and one or two supporting the rear muffler. A quick visual check on a hoist or referencing the VIN in a parts catalogue will confirm your car’s count.

What are the signs an exhaust mount needs replacing?
Look and listen for a sagging or off-centre tailpipe, new knocks over bumps, a buzz or drone at certain revs, and cracked or stretched rubber. If the muffler sits close to the bumper or bangs the rear beam, the mounts are likely tired.

Can universal hangers be used on a Pulsar?
They can, provided the hole spacing and thickness match, and the durometer (stiffness) is similar to OE. Too soft and the system will sag, too hard and you’ll feel more vibration. When in doubt, use OE or a quality aftermarket part designed for the B17/C12 platform.
