Parts for your 2016 Holden Barina-Exhaust mount

2016 Holden Barina exhaust mount: purpose, maintenance and replacement

Technical references confirm the 2016 Holden Barina (TM series) is fitted with exhaust mounts, also called exhaust hanger insulators. The GM Holden TM Barina Workshop/Service Information (Exhaust System – Muffler/Resonator procedures) specifies removing and refitting rubber hanger insulators during exhaust work, and the GM Global EPC (exhaust group) lists “Insulator – Exhaust System” for the TM. Common parts catalogues from ACDelco/GM Genuine Parts and Mackay Rubber also list Barina-specific exhaust hanger insulators. So yes—this Barina uses exhaust mounts.

On the 2016 Barina, these rubber mounts suspend the exhaust from the body, isolating engine and road vibration while keeping the pipework aligned under the car. Their job is simple but crucial: keep the cat-back and muffler from knocking on the subframe, beam axle, heat shields, and bumper, and let the system expand and move without transmitting noise into the cabin.

Over time, heat, road grime, and a bit of spirited driving can perish the rubber. When the mounts sag or crack, the exhaust can sit low, rattle over bumps, or thud on start-up and shutdown. Owners often notice a droopy tailpipe, new vibrations at idle, or a tinny rattle around the centre section.

Replacement is straightforward for a technician and very doable at home with stands and basic hand tools. Let the exhaust cool fully, support the pipe with a jack and wood block, spray the old rubbers with silicone lube, then lever them off the hangers. Fit the new insulators, check clearances to the rear beam, heat shields, and bumper, and make sure the tips sit even. If one mount has failed, it’s smart to replace the set so the system sits square.

• Inspect the mounts at each service (around 10,000–15,000 km) or after any underbody knock.
• Look for splits, hardening, or elongation of the holes, light surface cracking is a sign they’re ageing.
• Choose OE-style rubber for comfort, or polyurethane for firmer support if the car runs an aftermarket exhaust.
• If the exhaust still taps after new mounts, check for bent hangers, missing heat-shield clips, or a misaligned clamp.

Barina hatch and sedan layouts can vary slightly, but typically there are mounts at the rear muffler and mid-pipe, with an isolator near the front section. A VIN check against the EPC helps confirm exact locations and part numbers.

Popular questions

How many exhaust mounts does a 2016 Holden Barina have?
The TM Barina generally uses three to four hanger insulators depending on hatch or sedan and the exact exhaust spec. Expect one at the rear muffler, one around the centre section, and one near the front pipe. A quick look on a hoist or a VIN check in the parts catalogue will confirm the count on a specific car.

What are the signs the exhaust mounts need replacing on a Barina?
Common clues are a drooping tailpipe, new rattles over bumps, a thud at start-up or shutdown, and vibrations felt in the cabin. Visual inspection may show perished rubber, splits, or elongated holes allowing excess movement.

Can a DIYer replace the exhaust mounts at home?
Yes—if the car is safely supported, the exhaust is cool, and the right tools are on hand. A silicone spray, pry bar, and sturdy stands make the job manageable. Support the exhaust while swapping rubbers and check clearances before driving.
