Car Exhaust Repairs Dublin
If your car has suddenly become louder, you can hear a rattle underneath it, or you have noticed an unusual exhaust smell, it is worth getting it checked before the problem gets worse.
BNT Autos provides car exhaust repairs and exhaust checks from our workshop in Baldoyle, Dublin 13. We work on cars and light commercial vehicles from across North Dublin.
We will inspect the exhaust, find the source of the problem and let you know what actually needs to be repaired or replaced.
Car exhaust problems we can check
Exhaust faults can show up in a few different ways. You may notice:
- A louder exhaust than normal
- Blowing or hissing sounds
- Rattling underneath the car
- Exhaust fumes or unusual smells
- A knocking sound over bumps
- Reduced performance
- Increased fuel consumption
- An engine management light
- A failed or poor emissions result at the NCT
- Part of the exhaust hanging lower than it should
Sometimes the problem is obvious. Other times the noise can travel through the exhaust system and make it difficult to tell where the fault actually is.
That is why we prefer to inspect the car first rather than assume the whole exhaust needs replacing.
Exhaust leaks
A blowing exhaust is one of the most common problems we see.
Leaks can develop around joints, pipes, flexible sections, silencers or other parts of the exhaust system. Corrosion is also common, particularly on older cars or cars that spend most of their time on short journeys.
A small leak may only make the car noisier at first, but it can become worse over time. If you hear a blowing or hissing sound when accelerating, bring the car in and we can check where it is coming from.
Rattling or knocking from the exhaust
A rattle underneath the car does not necessarily mean you need a complete new exhaust. It can be something as straightforward as:
- A loose exhaust mounting
- Worn rubber hangers
- A damaged heat shield
- A loose joint
- Internal damage inside a silencer
- Corrosion around a bracket or pipe
We can inspect the exhaust system and tell you whether the problem can be repaired or whether a section needs to be replaced.
Car exhaust repairs
Depending on what we find, exhaust work may include:
Exhaust leak repairs
Replacement exhaust sections
Silencer replacement
Exhaust mounting replacement
Flexible pipe repairs
Exhaust pipe replacement
Investigation of rattles and knocking
Exhaust sensor diagnostics
Emissions-related fault finding
We will always explain what is required before carrying out the repair.
Exhaust warning lights and emissions problems
Modern car exhaust systems are connected to a number of sensors and emissions-control components.
If the engine management light is on, or the car has failed an emissions test, the problem may not simply be a damaged exhaust pipe. It can involve sensors, the catalytic converter, the DPF system on a diesel car or another engine-related issue.
BNT Autos can carry out diagnostics to help identify the cause rather than replacing parts unnecessarily. If the problem relates specifically to a diesel particulate filter, see our dedicated DPF Cleaning & Diagnostics service.
Car exhaust checks before the NCT
If your NCT is coming up and the car exhaust sounds louder than normal, it makes sense to have it checked beforehand.
An exhaust leak, damaged mounting or emissions issue can cause problems at test time. We can inspect the system and advise you on anything that needs attention before the car goes for its NCT.
Cars and vans
We carry out exhaust work on a wide range of cars and light commercial vehicles. If you are unsure whether we can work on your particular vehicle, contact us with your registration, make and model.

Car exhaust FAQs
Why has my car exhaust suddenly become loud?
A sudden increase in exhaust noise can be caused by a split pipe, failed joint, damaged flexible section or hole in the exhaust system.
Can a car exhaust be repaired rather than replaced?
In some cases, yes. It depends on where the damage is and the condition of the surrounding exhaust components. We will inspect it before recommending the best option.
Why is my exhaust rattling?
Common causes include loose mountings, heat shields, worn brackets or damage inside a silencer.
Can an exhaust problem cause the engine management light to come on?
Yes. Sensors and emissions components within the exhaust system can trigger warning lights when a fault develops.
Should I get my exhaust checked before an NCT?
If it is noisy, leaking, rattling or you have an emissions warning, it is worth having it checked before the test.
