2008 Nissan Primera Exhaust Mount — What It Does and When to Replace It

Based on technical references including the Nissan Primera P12 Service Manual (Exhaust System/EM section), the Nissan Electronic Parts Catalogue (EPC/FAST) listings for P12 exhaust mounting insulators, and the Haynes Nissan Primera (2002–2007) manual’s exhaust removal procedure, this vehicle uses exhaust mounts (rubber hangers/insulators). Although European production of the Primera ended in 2007, many cars were first registered in 2008, the 2008 Nissan Primera on the P12 platform retains the same exhaust mounting setup. So yes—an exhaust mount is absolutely relevant to this model.

The exhaust mount on a 2008 Nissan Primera supports the weight of the front pipe, catalytic converter, centre section and rear muffler, isolating vibration so the cabin stays quiet and the system doesn’t thump the body over bumps. These rubber insulators also keep the exhaust aligned, which helps prevent leaks at joints and reduces stress on flanges and flex sections. A few strategically placed mounts let the system move slightly as it heats and cools, while still holding it clear of heat shields, the subframe and the rear bumper.

As part of routine servicing, it’s smart to inspect the exhaust mounts every 10,000–15,000 km or at each service interval. Look for cracks, splitting, glazing/hardening, elongation of the holes, or any sign the exhaust is sitting low or knocking at idle. If one mount is tired, the others usually aren’t far behind—replacing them in pairs or as a set keeps everything level and quiet. OE-style rubber hangers are the best bet for factory comfort, firmer polyurethane options can sharpen support but may pass a bit more vibration into the cabin.

Replacement is straightforward with the car safely supported, the exhaust cool, and the system lightly supported by a jack or strap. A spritz of silicone spray or penetrating oil helps slide old rubbers off the pegs. Fit the new insulators in the same orientation, check clearances all round, and nip up any bracket fasteners to spec. While there, eyeball the steel hanger rods and brackets for rust or bends and replace anything suspect. Common tell-tales for worn mounts include a metallic rattle at idle, a clunk over speed humps, or the tailpipe sitting off-centre in the bumper cut-out. Sorting the mounts early protects the flex joint, keeps fumes where they belong, and restores that tidy, factory-fresh exhaust note.

• Signs it’s time: rattles, banging over bumps, sagging tailpipe, or exhaust tip misalignment
• Good practice: inspect at each service, replace in pairs, confirm clearances and bracket condition

FAQs

Where are the exhaust mounts on a 2008 Nissan Primera?

They’re positioned along the exhaust path on steel hanger pegs—typically near the rear muffler, around the centre section, and closer to the front pipe area. Their job is to hold the system up while isolating vibration, so expect several mounts spread from the mid-pipe to the tail.

How often should the exhaust mounts be replaced?

There’s no fixed kilometre limit. Inspect them at each service and replace when the rubber shows cracking, hardening, elongation, or if the exhaust is knocking or sitting low. Coastal cars or vehicles that do lots of short trips may need them sooner due to heat cycles and corrosion.

Can polyurethane hangers be used instead of rubber?

Yes, polyurethane hangers can add support and durability, especially on cars with heavier aftermarket systems. However, they can transmit more vibration. For everyday driving and factory NVH, OE-style rubber is usually the preferred choice.
