Parts for your 2008 Nissan Serena-Exhaust mount

2008 Nissan Serena Exhaust Mounts

Exhaust mounts are absolutely used on the 2008 Nissan Serena (C25). Nissan’s C25 Serena Service Manual (Exhaust System – EX section) and the Nissan FAST electronic parts catalogue both show the exhaust pipe, centre muffler and rear muffler supported by rubber insulators/hangers—commonly called exhaust mounts. So they’re relevant, fitted from factory, and essential to how the Serena’s exhaust is suspended and isolated from the body.

On this model, the mounts are tough rubber pieces that cradle the exhaust on metal pegs, keeping the system correctly aligned while soaking up vibration. That means fewer rattles in the cabin, less stress on joints and welds, and room for the exhaust to move slightly as it heats and cools. Depending on variant (2WD/4WD, wheelbase, and muffler layout), there are typically three to five mounts positioned near the front pipe, mid-section and tail muffler.

Over time, rubber can harden, crack or stretch. When Serena mounts start to perish, drivers may hear a knock over bumps, a metallic rattle at idle, or notice the tailpipe sitting off-centre. Left too long, a sagging system can strain the flex joint or flange gaskets, potentially leading to leaks.

As part of regular servicing, it’s smart to give the mounts a once-over every 10,000–15,000 kilometres or annually, especially if the vehicle tows, does lots of short trips, or lives near the coast. Replacement is straightforward and affordable, and it’s a good idea to swap them in sets on the affected section so the exhaust height stays even.

• Check for splits, tears, excessive softness, or elongation of the holes.
• Listen for knocks on start-up, over speed humps, or on rough roads.
• Support the exhaust with a stand before removing any mount.
• Use silicone spray or soapy water to help slide the new mount on.
• Avoid levering on the catalytic converter or flex pipe, handle by pipes and mufflers.
• Choose quality OEM-equivalent rubber, stiffer polyurethane is an option if extra support is needed, but may pass more vibration.

Most owners can expect 5–10 years from factory mounts, but climate and driving make a big difference. If there’s any sign of contact with the body, visible droop, or fresh exhaust vibration, replacing the mounts is cheap insurance for the Serena’s exhaust and everyone’s comfort.

How many exhaust mounts does a 2008 Nissan Serena have?

Most C25 Serenas run three to five rubber mounts, typically one near the front/centre and two around the rear muffler. The exact count can vary with 2WD vs 4WD and the specific exhaust layout. A quick look under the vehicle will confirm the positions.

What are the signs the Serena’s exhaust mounts need replacing?

Tell-tales include a dull knock over bumps, a buzz or rattle at idle, the tailpipe sitting crooked, or the exhaust tapping a heat shield. Any visible cracking, splitting, or a mount that’s gone soft and stretched means it’s time to replace.

Can polyurethane mounts be used on a Serena?

Yes, polyurethane hangers can add support and resist heat and oil better than standard rubber. They may transmit a touch more vibration into the cabin, so they suit vehicles that carry heavier loads or see rough roads, while many daily drivers are well served by quality OEM-style rubber.
