Parts for your 1999 Nissan Pulsar-Exhaust mount

1999 Nissan Pulsar Exhaust Mount

Yes, the 1999 Nissan Pulsar (N15 series) uses exhaust mounts. Technical references including the Nissan N15 factory service manual (Exhaust System section), the Nissan FAST parts catalogue (listing “insulator–exhaust” for multiple positions), and aftermarket catalogues from brands like Bosal and Mackay Rubber all identify rubber exhaust hangers/mounts fitted to the centre and rear sections of the system. They’re essential for suspending the exhaust under the car, isolating vibration, and keeping the pipework aligned.

On an N15 Pulsar, the exhaust mounts are rubber insulators that hook between chassis brackets and the exhaust’s welded pegs. Their job is simple but critical: tame vibrations, stop the muffler and pipes knocking on the floorpan, and maintain correct clearances to the bumper and suspension. When they harden, crack, or stretch, the exhaust can sag or move about, leading to rattles, clunks over bumps, and premature stress on joints and the flex section.

As part of servicing, it’s smart to give the mounts a look every 10,000–15,000 km or at each oil change. A quick inspection on a hoist or with the car safely supported will show perishing, splits, or elongated holes. Also check for oil contamination (rubber doesn’t love engine oil), rust on the hanger hooks, and any contact marks on the subframe or heat shields. If the tailpipe looks off-centre in the bumper cut-out or the system knocks at start-up, that’s a big hint the mounts are tired.

Replacement is straightforward with basic tools. Support the exhaust with a jack or stand, spritz the old rubbers with silicone spray, and lever them off the pegs. Fit quality replacements—genuine-style rubber for OE comfort, or firmer performance-spec insulators if the car runs a larger aftermarket system. Re-check clearances around the rear beam, sway bar, and bumper. If clamps or joints were loosened, snug them up to the manufacturer’s torque guidance. Given the cost of new insulators is relatively low, it’s often worth replacing the full set together to restore proper alignment.

• Typical symptoms: rattles over bumps, buzzing at idle, exhaust sagging, or the tip touching the bumper.
• Good practice: inspect every service, replace at the first signs of cracking or excessive movement.
• Tech references: Nissan N15 FSM (Exhaust), Nissan FAST parts listings for “insulator–exhaust”, Bosal/Mackay Rubber fitment catalogues.

Popular questions about 1999 Nissan Pulsar exhaust mounts

How many exhaust mounts does a 1999 Pulsar have?
Most N15 Pulsars run three to four rubber insulators, typically at the centre pipe and around the rear muffler. Exact count can vary with body style and exhaust configuration. A quick visual check or a look-up by VIN in the Nissan FAST catalogue confirms your specific layout.

What are the signs my Pulsar’s exhaust mounts need replacing?
Listen for knocks over speed humps, a metallic rattle at idle, or see if the tailpipe sits low or off-centre. Cracked, hardened, or oil-soaked rubbers, or elongated mounting holes, are clear indicators. Any contact marks on the floorpan or heat shields also point to failed mounts.

Can I use stiffer aftermarket mounts?
Yes—firmer polyurethane or heavy-duty rubber mounts can control movement better, handy for bigger exhausts. Expect a small increase in vibration transmitted to the cabin. For a daily driver, OE-style rubber remains the most comfortable choice.
