1999 Nissan Primera Exhaust Mount: Purpose, Service and Replacement

Technical sources confirm that the 1999 Nissan Primera (P11) is fitted with exhaust mounts (also called exhaust insulators or hangers). The Nissan Primera P11 Service Manual (EX – Exhaust System section), the Nissan FAST Electronic Parts Catalogue for P11 (Group 20 Exhaust, showing “Insulator–Exhaust” and related brackets), and common aftermarket catalogues from brands like Bosal and Walker all identify multiple rubber mounting insulators for this model. So yes, an exhaust mount is absolutely relevant to the 1999 Primera.

On this Primera, the exhaust mounts are tough rubber insulators that suspend the exhaust system from the body. Their job is to isolate vibration, keep the pipework aligned, and allow a bit of movement so heat expansion and road bumps don’t crack welds or stress the manifold. Typically, the P11 has a hanger near the front pipe/catalyst area, one around the centre section, and another at the rear muffler. Some variants add an extra mount depending on the exhaust layout.

When these mounts age, the rubber hardens, cracks, or stretches. That can lead to clunks over bumps, an annoying rattle at idle, a tailpipe that looks crooked, or the exhaust knocking the floor under acceleration. Left too long, a sagging system can stress joints and flanges, or even damage the bumper.

As part of regular servicing, it’s smart to inspect the exhaust mounts every service or 20,000 km—more often if the car lives near the coast or tackles rough roads. Look for perished rubber, splits, elongation of the holes, or bent/rusty brackets. If one mount has failed, consider replacing the set so the system sits true.

Replacement is straightforward with the car safely on a hoist:

• Let the exhaust cool fully, support it with a stand, then remove the old insulators.
• Apply a little silicone spray to help slide the new mounts on.
• Check clearances around the subframe, heat shields and bumper, adjust as needed.
• Use quality OEM-equivalent rubber (EPDM) or a proven aftermarket insulator, avoid flimsy universals that don’t hold alignment.

Time-wise, allow 0.3–0.7 hours per mount depending on rust and access. A quick check and timely replacement keeps the Primera quiet, comfy, and protects the rest of the exhaust from avoidable drama.

Popular questions

How many exhaust mounts does a 1999 Nissan Primera have?
Most P11s run three to four mounts: one up front near the catalyst/front pipe, one around the centre resonator, and one at the rear muffler. Some trims or aftermarket systems add an extra hanger. A quick look underneath will confirm what’s fitted to a specific car.

What are the signs the exhaust mounts need replacing on a P11?
Common signs include a rattle at idle, clunks over bumps, a tailpipe sitting off-centre, or vibration inside the cabin. Visible cracks, stretched holes in the rubber, or a sagging muffler are dead giveaways.

Can universal exhaust hangers be used on a 1999 Primera?
Yes, quality universal EPDM hangers can work if the hole spacing and thickness suit the brackets. That said, OEM-shaped insulators usually centre the system better and reduce the chance of contact under load.
