Parts for your 2020 Nissan Serena-Exhaust mount

2020 Nissan Serena exhaust-mount: what it does and when to replace it

Exhaust-mounts (also called exhaust hangers or insulators) are absolutely used on the 2020 Nissan Serena (C27). Nissan’s C27 Service Manual – Exhaust System (EX) section – specifies rubber insulators that suspend the exhaust, and the Nissan Electronic Parts Catalogue (FAST/EPC) lists multiple exhaust mounting insulators for the mid-pipe and rear muffler on C27 Serena variants, including e-POWER models. So the part is relevant to this vehicle.

On the Serena, the exhaust-mount’s job is to hold the exhaust system in place while isolating vibration and noise from the cabin. Heat-resistant rubber insulators sit on metal hanger pegs attached to the body and the exhaust, letting the system move slightly without banging into the underbody. The C27 typically uses three to four mounts: commonly one around the centre section and two at the rear muffler (some variants add another near the front pipe). This keeps the long exhaust run supported and aligned, protecting the catalytic converter, flex joint and muffler welds from stress.

As part of regular servicing, it’s smart for Serena owners to have the exhaust-mounts checked. In Australian and New Zealand conditions—heat, UV, coastal air, and corrugations—the rubber can harden, crack or perish over time. Inspection every service (roughly 10,000–15,000 km) is a good habit, and sooner after any underbody impact or if the exhaust has been removed for other work.

• Replace if the rubber is cracked, split, sagging or oil-soaked.
• Watch for symptoms: exhaust knocking over bumps, a droopy tailpipe, rattles at idle, or the tip sitting off-centre in the bumper cut-out.

Replacement is straightforward when done correctly: support the exhaust so it doesn’t strain joints, lubricate the hangers with silicone spray, swap the insulators, then confirm clearances to heat shields, suspension and the rear bumper. If one mount has obviously failed, checking and often replacing the adjacent mounts is wise—they usually age together. Using OE or high-quality aftermarket insulators that match Serena C27 specs maintains the correct ride height and isolation. After fitting, a quick road test over small bumps helps confirm there’s no contact or new rattles.

Keeping these little mounts healthy reduces cabin noise, prevents annoying knocks, and protects more expensive exhaust components. They’re inexpensive insurance for a people-mover that often carries a full load and sees plenty of urban stop-start work.

Popular questions about 2020 Nissan Serena exhaust-mount

How many exhaust-mounts are on a 2020 Nissan Serena?
The C27 Serena generally uses three to four rubber insulator mounts, with two supporting the rear muffler and one or two along the mid/front sections depending on the exact variant. The Nissan FAST/EPC listings for C27 corroborate these positions. A quick visual check on a hoist will confirm the count on a specific vehicle.

What are the signs an exhaust-mount needs replacing on a Serena?
Common signs include a tailpipe that sits lower or off-centre, a dull knock over speed humps, rattling at idle, or visible cracks and splits in the rubber. If a mount fails, the extra movement can stress joints and gaskets, so it’s best to sort it early.

Is it safe to drive with a broken exhaust-mount?
Short distances might be possible, but it’s not recommended. A broken mount can let the exhaust hit the body, damage sensors or welds, or in severe cases drag on the road. Replacing the insulator promptly helps avoid bigger repair bills and keeps the ride quiet and tidy.
