1994 Nissan Primera Exhaust Mounts — What They Do and How to Look After Them

Yes, the 1994 Nissan Primera (P10) is fitted with exhaust mounts. Technical sources that document this include the Nissan Factory Service Manual (P10 FSM), the Nissan FAST electronic parts catalogue (showing multiple exhaust “mounting insulators”/hangers along the system), the Haynes Nissan Primera 1990–1999 service manual, and aftermarket catalogues from Bosal and Walker that list replacement exhaust mounting rubbers for the P10. That means an exhaust-mount is absolutely relevant on this model.

On a ’94 Primera, the exhaust mounts (often called hangers or insulators) keep the exhaust system supported and correctly positioned from the front pipe right through to the rear muffler. They’re designed to isolate vibration, allow a bit of movement as the engine twists and the system heats up, and stop the pipework from knocking the body, subframe or suspension. Good mounts protect the manifold, catalytic converter and joints from stress, helping to avoid cracks and leaks.

As these cars age, the rubber can harden, crack or stretch. Heat, road grime and the odd oil leak can all speed that up. During regular servicing (every 10,000–15,000 kilometres is a tidy rhythm in Aus and NZ), a quick under-car check is well worth it: if the muffler looks droopy, the tailpipe sits off-centre, or there are fresh rub marks near heat shields, chances are a mount’s on the way out.

Replacement is straightforward with the right approach. Support the exhaust with a jack and a block of wood so it doesn’t strain the remaining mounts. A spritz of silicone spray helps the old rubbers slide off and the new ones slip on—avoid petroleum grease as it can attack the rubber. Refit any brackets and tighten hardware to factory spec per the FSM, and make sure clearances are even around the rear bumper and suspension arms.

Choosing parts is simple: OE-style rubber insulators are quiet and comfy, polyurethane options are tougher but can pass a bit more vibration into the cabin. On a daily-driven Primera, most owners prefer OE-type rubbers. If one mount has failed, it’s smart to replace any others that look perished—doing them in pairs keeps the system sitting square. A tidy, rattle-free exhaust won’t just sound better, it also helps with roadworthy/WOF checks and keeps the cabin peaceful on long hauls.

• Common signs to watch: clunks over bumps, rattles at idle, sagging tailpipe, or the exhaust tapping a heat shield.
• Good extras while you’re there: inspect heat shields, check bracket welds, and eyeball the flex section for splits.

Popular questions about 1994 Nissan Primera exhaust mounts

How many exhaust mounts does a 1994 Nissan Primera have?
It varies slightly with body style and exact exhaust layout, but typically there are three to five rubber hangers from the front/centre section to the rear muffler. The Nissan FAST parts catalogue for the P10 shows multiple mounting insulators, a quick look under the car or a VIN-based parts lookup will confirm the exact count.

Can polyurethane exhaust mounts be used on a Primera P10?
They can, and they’re durable, but they’re firmer than OE rubber and can transmit more vibration into the cabin. For a comfortable daily driver, OE-style rubber is usually the go. If chasing a tighter, sportier feel and don’t mind a touch more buzz, polyurethane is an option.

What are the tell-tale signs an exhaust mount needs replacing?
Rattles at idle or on start-up, thuds over speed bumps, a sagging rear muffler, or the tailpipe sitting off-centre are all giveaways. Any cracks, splits or stretched holes in the rubber, or oil-soaked mounts, mean it’s time to swap them out.
