Exhaust Repairs, Replacement & Diagnostics
Maybe you’ve noticed a rattling noise underneath the car, reduced performance, a warning light or an MOT failure linked to the exhaust or emissions system.
DB Autos provides professional exhaust fitting and exhaust repairs in Stoke-on-Trent for a wide range of makes and models.
Our exhaust services can include:
The exhaust system does far more than keep the car quiet. It carries gases away from the engine, helps control emissions and plays an important role in how the vehicle performs. If your exhaust sounds different or you suspect a problem, get it checked before a small leak turns into a much bigger repair.
Exhaust problems often give drivers plenty of warning.
Common signs include:
Exhaust Suddenly Sounds Louder
A hole, split joint or failed exhaust section can dramatically increase exhaust noise.
Rattling Under the Car
Loose brackets, damaged mountings or internal exhaust components can cause rattling.
Blowing or Hissing Noise
A leak can create a blowing or hissing sound, particularly when the engine is running or under acceleration.
Reduced Engine Performance
Restrictions or certain exhaust faults can potentially affect engine performance.
Engine Warning Light
Problems involving emissions components or sensors may trigger a warning light.
Unusual Smells
Exhaust fumes should never be entering the cabin. If you smell fumes inside the vehicle, get the system inspected promptly.
MOT Failure
Exhaust leaks, excessive emissions and certain damaged components can all lead to MOT problems.
Not every exhaust problem means the complete system needs replacing.
Exhaust systems are generally made up of several sections.
Depending on the vehicle, these may include:
If one section is defective and the rest of the system is still in good condition, it may be possible to replace only the affected part. DB Autos will inspect the exhaust and tell you what actually needs attention.
An exhaust leak may produce:
Leaks can occur around:
The correct repair depends on the location and condition of the system.
Silencers help reduce engine and exhaust noise.
If a silencer becomes corroded or damaged, the car may become noticeably louder.
You may also hear rattling from inside the silencer if internal components have deteriorated.
DB Autos can inspect the affected section and replace it where necessary.
The rear silencer or back box is one of the exhaust components most exposed to road spray, salt, moisture and corrosion.
Signs of deterioration can include:
If the back box has reached the end of its useful life, we can supply and fit the appropriate replacement.
The catalytic converter helps reduce harmful pollutants in exhaust gases.
Problems can arise through:
Possible symptoms include:
A faulty catalytic converter should not automatically be replaced without checking why it failed. If an engine fault caused the damage, fitting another converter without fixing that problem can lead to another failure.
An emissions failure doesn’t always mean the exhaust itself is the only problem.
Possible causes can involve:
DB Autos provides vehicle diagnostics alongside exhaust repairs, allowing us to investigate the wider problem.
Modern vehicles use oxygen sensors, often called lambda sensors, to monitor oxygen levels in the exhaust gases.
This information helps the ECU adjust fuelling.
A sensor fault can contribute to:
If a warning light is present, diagnostic testing can help identify whether the sensor itself or another engine problem is responsible.
Certain exhaust systems use a flexible section to absorb engine movement and vibration.
These sections can deteriorate and begin leaking.
Symptoms can include:
DB Autos can inspect the exhaust and advise on the appropriate repair.
The exhaust system is supported underneath the car by brackets, hangers and rubber mountings.
If one fails, the exhaust may:
A damaged mounting can sometimes be a relatively straightforward repair, but leaving it can cause further damage elsewhere in the exhaust.
Exhaust systems operate in a particularly unpleasant environment.
They deal with:
Over time, corrosion can weaken pipes and silencers until holes or splits develop. Short journeys can also contribute to condensation remaining inside the exhaust because the system doesn’t always get hot enough to evaporate all the moisture.
Yes.
An MOT can identify problems involving:
DB Autos is also an MOT test centre, which means we can handle many exhaust-related MOT repairs as well as the test itself.
If your exhaust is already blowing, rattling, excessively loud or hanging down, it’s worth getting it checked before your MOT.
A quick inspection may identify something straightforward before it becomes an official failure.
And if the vehicle does fail, DB Autos can advise on the repairs required.
Yes, certain exhaust faults can affect performance.
A badly restricted catalytic converter or other exhaust restriction can potentially cause:
Not every performance problem originates with the exhaust, which is why diagnosis matters.
