Parts for your 2017 Holden Barina-Exhaust mount

2017 Holden Barina Exhaust Mount

Yes, the 2017 Holden Barina (TM, based on the GM T300 platform) uses exhaust mounts. Technical sources including the Holden/GM Service Information for the T300 exhaust system and the Holden/GM parts catalogue list dedicated “exhaust hanger insulators” and brackets at the centre section and rear muffler, confirming the vehicle is fitted with exhaust mounts.

On a 2017 Holden Barina, the exhaust mount (also called a hanger, insulator, or rubber mount) is the small but mighty component that suspends the exhaust system from the underbody. Its job is to isolate vibration, keep the pipework correctly aligned, and stop the muffler from knocking on the body or rear suspension. When the rubber perishes, stretches, or cracks, the exhaust can sag, rattle, or thump over bumps, and cabin noise can creep up. Left too long, a drooping system can stress welds and flanges, leading to bigger repair bills.

As part of routine servicing, it’s smart to inspect the Barina’s exhaust mounts every service interval, or at least every 15,000 km. Look for dried, split, or oil-soaked rubber, elongated holes, or shiny contact marks near the exhaust that suggest it’s been touching the body. A bar of silicone spray on stubborn hangers helps with removal without tearing the rubber.

Replacement is straightforward with basic tools: safely raise and support the car, support the exhaust with a jack, and swap the old insulators one at a time. Reuse the factory brackets if they’re sound, and make sure the tailpipe sits centred in the bumper cut-out with decent clearance all round. If the vehicle sees rough roads or carries heavy loads, consider quality OEM-spec rubber or a performance polyurethane insulator, just note that very stiff mounts can add a touch more vibration. Many Barinas will have three to four mounts depending on exhaust layout—front/centre support and one or two at the rear muffler. A workshop can usually sort the lot in under an hour, and parts are inexpensive, making this a tidy preventative fix that keeps the Barina quiet, rattle-free, and compliant with roadworthy standards.

• Check mounts at each service or if you hear exhaust rattles.
• Replace in pairs if wear is similar across the system.
• After fitting, recheck clearances with the engine running and in gear (foot on brake) to confirm no contact under load.

How many exhaust mounts does a 2017 Holden Barina have?

Most TM Barina hatches run three to four rubber hangers: one supporting the front/centre section and two around the rear muffler. Exact count can vary with trim and whether there’s a mid-resonator. A quick visual check under the car will confirm the layout.

What are the signs the exhaust mounts need replacing?

Common giveaways include a rattly exhaust at idle, thumps over bumps, the tailpipe sitting low or off-centre, and visible cracks or stretching in the rubber insulators. If the exhaust has started touching heat shields or the rear beam, the mounts are likely tired.

Can a home mechanic replace the mounts, and how long does it take?

Yes. With stands or ramps, a jack to support the exhaust, and some silicone spray, a home mechanic can swap the insulators. Budget 30–60 minutes. If bolts are rusty or alignment looks off, a workshop can handle it quickly and check for any extra exhaust leaks while they’re there.
