Parts for your 2011 Nissan Pulsar-Exhaust mount

2011 Nissan Pulsar exhaust-mount: what it does and how to look after it

Yes, an exhaust-mount is used on the 2011 Nissan Pulsar. Nissan’s Electronic Service Manual for the platform sold in this region around 2011 (C11-series, commonly known as Tiida in AU/NZ but directly comparable to the Pulsar line) specifies rubber exhaust insulator hangers at multiple points along the system. The Nissan FAST parts catalogue also lists “Insulator – Muffler” (exhaust hangers) for 2011 vehicles in this family. Those technical sources confirm the exhaust is supported by several rubber mounts between the exhaust piping/mufflers and the body.

On a 2011 Pulsar, the exhaust-mount (often called a hanger or insulator) is a small but crucial bit of rubber that suspends the exhaust so it can move slightly without knocking the body. It soaks up engine vibrations, keeps the tailpipe centred in the bumper cut-out, and prevents stress cracking at welds and flanges. Without healthy mounts, the exhaust can sag, rattle on start-up, thump over bumps, or even rub on heat shields and subframes.

There isn’t a fixed change interval for exhaust-mounts, but they’re a wear item. In Aussie and Kiwi conditions—heat, road grime, the odd gravel road—rubber can harden or perish. A good rule is to inspect them at each service (every 10,000–15,000 km) or whenever the car is on a hoist for tyres, brakes or WOF checks. Look for splits, elongation of the holes, shiny rub points on the exhaust, or a muffler that sits off-centre.

Replacement is straightforward and cost-effective:

• Let the exhaust cool completely, support the pipe/muffler, and spray the old mounts with silicone lube for easy removal.
• Fit OEM-equivalent rubber insulators. Polyurethane hangers are stiffer but can add cabin vibration, fine for sporty feel, not ideal if chasing comfort.
• Check bracket welds and bolts for corrosion, set clearances around heat shields, bumper and suspension arms, and replace mounts in pairs/sets if most are the same age.

After fitting, ensure the system sits naturally (no pre-load) and that the flex joint isn’t pulled tight. A fresh set of mounts can quieten buzzes and protect O2 sensor wiring and flanges, helping the Pulsar pass a WOF and stay tidy on long Kiwi and Aussie drives.

How many exhaust-mounts does a 2011 Nissan Pulsar have?

Most 2011 Pulsar/Tiida variants run three to five rubber insulators, typically near the front pipe, centre resonator and rear muffler. Exact count depends on body style and whether it has a centre resonator. A quick look on a hoist will confirm the locations.

What are the signs the exhaust-mounts need replacing?

Tell-tales include rattling at idle or on start-up, thumps over bumps, a tailpipe that’s off-centre or touching the bumper, and visible cracks or stretched holes in the rubbers. You might also notice new vibrations in the cabin or a muffler sitting lower than usual.

Is it safe to drive with a broken exhaust-mount?

It’ll usually move under its own steam, but it’s not ideal. A failed mount can stress the flex joint, crack welds, chafe O2 sensor wiring, or let the system hit the underbody. Short trips to a workshop are generally fine if the exhaust isn’t dragging—otherwise, sort it promptly.
