Parts for your 2014 Mazda Premacy-Exhaust mount

2014 Mazda Premacy exhaust mount — what it does and when to replace it

Exhaust mounts are absolutely used on the 2014 Mazda Premacy (Mazda 5, CW series). Technical sources including the Mazda 5 (CW) Workshop Manual (2012–2015, Exhaust System — Removal/Installation) and Mazda’s Electronic Parts Catalogue for MY2014 list multiple rubber exhaust hangers and associated brackets supporting the centre pipe and rear muffler. These mounts are factory-fitted to suspend the exhaust beneath the vehicle and isolate vibration.

The exhaust mounts (rubber hangers) keep the pipework and mufflers aligned, maintain safe clearance to the body and suspension, and soak up engine and road vibrations so the cabin stays quiet. They also protect welds, flanges, the flex section and the catalytic converter from undue stress by allowing controlled movement as the drivetrain shifts under load.

On a 2014 Premacy that’s had a fair few kilometres, those rubber bits can harden, crack or stretch from heat and age. That’s when owners start noticing knocks on start-up, a dull rattle over bumps, or a tailpipe sitting off-centre. Left too long, a sagging exhaust can contact the subframe or heat shields, or even crack a joint.

As part of routine servicing, it’s smart to inspect the exhaust mounts annually or every 10,000–15,000 km:

• Look for perished, split or oil-soaked rubber, check for elongated holes in the hangers.
• Confirm the muffler and pipes sit evenly with consistent body clearance.
• Check metal brackets for corrosion and loose fasteners, retighten to spec if needed.
• Lightly lubricate rubber hangers with silicone spray to reduce binding and squeaks.

Replacement is straightforward with the car safely supported. Back up the exhaust with a jack and timber block, then swap one hanger at a time so alignment stays true. A rubber-safe lubricant helps slide the old hanger off the pegs. Use quality, heat-rated hangers, consider firmer, high-temp versions if the vehicle tows or regularly carries a full load. If a mount has failed, it’s wise to check adjacent mounts and replace them as a set if they’re the same age.

Typical signs it’s time for new mounts:

• Rattle or thump near the rear under light acceleration or over corrugations.
• Tailpipe sitting low or touching the bumper cut-out.
• Visible cracks or a glossy, hardened look to the rubber.

Most Premacy exhaust mounts last 5–10 years, but climate, road conditions and heat cycles play a big role. For a 2014 model, proactive replacement can restore quietness and protect the rest of the exhaust.

Popular questions about 2014 Mazda Premacy exhaust mounts

How many exhaust mounts does a 2014 Mazda Premacy have?
The CW-series Premacy typically uses several rubber hangers from the front pipe through to the rear muffler—often three to four, depending on market spec and exhaust configuration. A quick visual from the centre section to the tailpipe will show each hanger supporting the system at key points.

What are the symptoms of a worn exhaust mount?
Owners usually hear a rattle, clunk or drumming from the rear, notice the tailpipe sagging, or feel extra vibration at idle. It can also sound like metal tapping the floor on bumps. If any of that shows up, a quick under-car check of the hangers and brackets is worthwhile.

Will a bad exhaust mount fail a WOF or roadworthy?
It can, if the exhaust is insecure or contacting the body, fuel lines or suspension. Inspectors look for proper support and clearance. Replacing perished hangers and tightening brackets generally sorts it, keeping the system quiet and compliant.
