Exhausts
Quieter, cleaner, MOT-ready
Your exhaust carries harmful gases away, keeps noise down and matters for passing the MOT. Leaks, corrosion or blockages cost fuel and can be a safety risk.
We diagnose and repair a wide range of exhaust problems — pipes, silencers, catalytic converters and oxygen sensors — using quality parts.
We can also inspect the system to catch problems before they turn into costly replacements.
- Pipes & silencersRepaired or replaced.
- Catalytic convertersDiagnosed and fitted.
- SensorsOxygen and exhaust sensors.
- EmissionsSorted before your MOT.
What the exhaust is doing
More than carrying fumes away. It keeps noise down, holds the sensors the engine management relies on to set the fuelling, and contains the catalytic converter and, on a diesel, the particulate filter that clean up what comes out. A leak upstream of a sensor can upset the running of the engine as well as the noise.
Signs of a problem
- It has got louder, or there is a drone or rasp that was not there before
- A rattle under the car, often worst at idle or over bumps
- A smell of exhaust fumes, particularly inside the car — get this seen to straight away
- Visible smoke, or soot around the tailpipe
- The engine management light on, or fuel economy that has dropped off
- Vibration through the floor at certain revs
The exhaust and the MOT
The MOT checks the system for leaks, security and excessive noise, and measures emissions against the limits for your vehicle. A blowing joint, a missing or ineffective catalytic converter, or emissions over the limit will all fail it. A rattling heat shield is a common and cheap one to sort before the test rather than after.
Exhausts: common questions
Can a section be repaired instead of replacing the whole system?
Often, yes — exhausts are usually made up in sections, and if the rest is sound there is no reason to replace it all. We will tell you which it is.
Why has my exhaust gone so loud all of a sudden?
Usually a joint that has blown or a corroded section that has finally given way. It is worth getting checked promptly — a leak can let fumes into the cabin.
What is a DPF and why does mine keep warning me?
A diesel particulate filter traps soot and burns it off once the exhaust is hot enough. Cars used mainly for short, cold journeys never get that chance and the filter clogs. If the light is on, get it looked at before it blocks completely.
Will a noisy exhaust fail the MOT?
It can — the test covers leaks, security and excessive noise, as well as the emissions readings. Better to sort it beforehand.
