2018 Toyota Vitz/Yaris Exhaust Mount – What It Is and When to Replace It

Technical sources confirm the 2018 Toyota Vitz/Yaris is fitted with exhaust mounts (also called exhaust hanger insulators). The Toyota Electronic Parts Catalogue (EPC) for the 2017–2019 Vitz/Yaris (model codes such as NSP130/NSP135/NSP150) shows multiple exhaust pipe support insulators at the centre pipe and rear muffler. Toyota’s Repair Manual (TIS) procedures for “Exhaust Pipe – Removal/Installation” specifically direct technicians to remove and refit these supports. Major aftermarket catalogues (e.g., Bosal/Walker) also list hanger insulators for the 2018 Yaris/Vitz. So yes—an exhaust mount is absolutely relevant and used on this model.

On a 2018 Toyota Vitz/Yaris, the exhaust mounts do the quiet, important work of holding the exhaust system in place while damping vibration. They’re rubber isolators that let the exhaust move a touch as the engine rocks and the pipework heats and cools, but stop it from banging on the body, subframe or suspension. That keeps the cabin calm, the tailpipe sitting straight, and sensitive parts like the flex joint and oxygen sensor wiring under less stress.

As part of regular servicing, it’s smart to have the exhaust mounts inspected. At every service or roughly every 20,000 km, a quick look for perished rubber, cracks, elongation, or oil contamination goes a long way. If the Yaris lives near the coast or does lots of short trips, check the metal hanger pegs for corrosion too. Typical tell-tales include knocks over bumps, a rattle at idle, a tailpipe that looks off-centre, or a thrum that changes with throttle.

When a mount’s past its best, replacement is straightforward for a workshop: support the exhaust, spray a little silicone lube, slip the tired insulator off and press a new one on. It’s often worth replacing any adjacent insulators at the same time so the system sits evenly. Quality OEM-style rubber keeps the factory comfort, firmer polyurethane can last longer but may pass a touch more vibration into the cabin.

A couple of practical tips for owners of 2018 Vitz/Yaris in Australia and New Zealand:

• If you hear exhaust tapping on cold start, don’t ignore it—loose mounting can crack the flex joint.
• After heavy rain or beach driving, rinse the underbody, salt accelerates hanger and bracket corrosion.
• For roadworthy/rego or WOF, an insecure exhaust can be a fail, so timely mount replacement helps avoid hassles.

Popular questions about 2018-toyota-vitz-yaris exhaust-mount

How often should exhaust mounts be replaced on a 2018 Toyota Vitz/Yaris?
There isn’t a fixed interval, they’re replaced on condition. Have them checked at each service. In Aussie and Kiwi conditions, many last well past 100,000 km, but coastal use, heat, and oil exposure can shorten their life. If you notice knocks, sagging, or a crooked tailpipe, it’s time to swap them out.

Will polyurethane exhaust mounts make a 2018 Vitz/Yaris noisier?
Poly mounts are tougher and resist stretching, which can sharpen up support. The trade-off is slightly firmer NVH. On a Yaris/Vitz most drivers won’t mind, but those chasing the quietest ride may prefer OEM-style rubber.

Is a cold-start rattle a mount or a heat shield on a 2018 Yaris/Vitz?
Both are common. A perished mount lets the exhaust tap the body, a loose heat shield buzzes at certain revs. A quick inspection on a hoist will spot torn insulators, shiny contact marks, or loose shield fasteners and guide the fix.
