Parts for your 2014 Holden Colorado-Exhaust mount

2014 Holden Colorado exhaust-mount – what it does and when to replace it

Yes, an exhaust-mount is absolutely used on the 2014 Holden Colorado. Technical references back this up: the Holden RG Colorado Service Manual (Exhaust System section) specifies multiple exhaust hangers/insulators and brackets supporting the pipework and muffler, the GM/ Holden parts catalogue for the RG platform lists exhaust mounting “insulator” rubbers and hanger brackets along the system, and Australian fitment catalogues from major rubber manufacturers include dedicated exhaust mounts for the Colorado RG (2012–2016). So, if the exhaust on a 2014 Colorado is rattling or sitting wonky, the mounts are right in the frame.

The exhaust-mounts (often called hangers or insulators) are the small but mighty rubber-and-metal supports that suspend the exhaust under the ute. Their job is to isolate vibration, keep the muffler and pipes aligned, and allow some movement as the driveline twists, all without letting the system knock on the chassis. On a workhorse like the Colorado, they cop heat, road grime, water crossings and the odd nudge off-road, so they can harden, crack or tear with age.

As part of routine servicing, it’s smart to eyeball the mounts anywhere the exhaust changes direction or near the muffler. Look for perished rubber, elongation of the holes, rusted brackets, or the exhaust sitting lower than usual. A quick wiggle test of the muffler will often show excessive play if a mount is on the way out. Many owners time mount replacement with other exhaust work, but there’s no harm in replacing a dodgy insulator on its own.

Replacement is straightforward for most DIYers with stands and basic hand tools. Let the exhaust cool completely, support the muffler so it doesn’t drop, then swap the insulators one at a time. A dab of silicone spray helps slide new rubbers onto the pegs. It’s good practice to replace mounts in pairs along the same section to keep alignment tidy. After fitting, check tailpipe clearance to the bumper and towbar, and verify there’s no contact with crossmembers through a gentle shake test.

• Common symptoms: clunks over bumps, exhaust drone/vibration in the cab, tailpipe not centred, visible split or sagging rubber.
• Service tip: inspect mounts at each service interval, especially if towing, doing corrugations, or after a scrape.
• Parts choice: quality OEM or reputable aftermarket rubber mounts last longer and ride quieter.

Popular questions about 2014 Holden Colorado exhaust-mount

How many exhaust mounts are on a 2014 Holden Colorado?
Most 2014 Colorado setups use several mounts spread from the front pipe to the rear muffler/tailpipe, typically three to five depending on cab/bed length and exact exhaust layout. The number can vary with trim and any previous exhaust modifications. A quick underbody look will confirm how many are on the vehicle in question.

What are the signs the exhaust mounts need replacing?
Tell-tales include new rattles or thumps over bumps, a deeper or buzzier exhaust note, the tailpipe sitting off-centre, or seeing cracked, stretched or missing rubber insulators. If the exhaust can be moved a long way by hand or taps the chassis, the mounts are likely tired.

Is it safe to drive with a broken exhaust mount?
It might get you home, but it’s not ideal. A failed mount can let the exhaust sag and knock, stressing other mounts and joints. In a worst case, a section could drop and get damaged. It’s best to support the system temporarily and replace the faulty mount as soon as practical.
