At Catman, the journey toward cleaner, more efficient motoring begins with the automobile converter. For more than two decades, our Hampshire-based team has supplied motorists, garages, and fleet managers across the globe with premium catalytic converters, diesel particulate filters, and complete exhaust systems. Whether you drive a compact city car, a diesel SUV, or a long-haul commercial van, the right automobile converter is the crucial component that transforms harmful exhaust gases into environmentally benign substances, unlocks smoother performance, and protects your engine from premature wear. Backed by a network of well-established OEM and aftermarket manufacturers, every automobile converter we ship carries at least a 12-month warranty, guaranteeing peace of mind alongside measurable emission reductions. Couple that reliability with our renowned speed of delivery, amazing value for money, and expert technical support via 01489 666 468, 01489 666 384, or 0207 1019 387, and it becomes clear why Catman is the smart driver’s first choice for emission-control components.
Understanding the Automobile Converter and Emission Control
The science behind modern vehicle-emissions control is both fascinating and vital. At the centre of that science sits the automobile converter, a compact yet sophisticated device engineered to convert toxic gases—carbon monoxide, hydrocarbons, and nitrogen oxides—into harmless water vapour, nitrogen, and carbon dioxide. Installed between the engine manifold and the rear exhaust, an automobile converter uses precious-metal catalysts such as platinum, palladium, and rhodium to speed up the necessary redox reactions at temperatures sometimes exceeding 800 °C. When the process is working as intended, drivers enjoy cleaner tail-pipe emissions, steadier idle, and improved fuel economy without sacrificing power.
Although the principle of catalytic conversion has not changed dramatically since the 1970s, today’s automobile converter must contend with tighter global emission standards, variable fuel qualities, and increasingly complex engine control units. That is why Catman partners only with manufacturers who subject every automobile converter to stringent thermal-shock, vibration, and flow-bench testing before it ever reaches our shelves. By combining advanced wash-coat technology with precisely measured substrate designs, the modern automobile converter achieves peak conversion efficiency within seconds of cold-start, thereby reducing the urban pollution spikes historically associated with short commutes. For wider context on how converters integrate with systems such as EGR valves, DPFs, and SCR units, explore this comprehensive emissions-control primer.
For drivers of specific marques—be it a BMW, Ford, or Nissan—our catalogue offers model-matched converters that drop straight into your existing exhaust system.
What Is an Automobile Converter?
Put simply, an automobile converter is a cylindrical or oval section of the exhaust system packed with a honeycomb ceramic or metal matrix. The matrix is coated with catalytic metals that accelerate chemical reactions needed to scrub the exhaust. Every automobile converter sold by Catman is engineered to match the flow rate, back-pressure, and emission profile of its target vehicle, ensuring a seamless drop-in replacement that keeps MOT and TÜV inspections hassle-free across Europe and beyond.

If you are comparing DPFs versus catalytic converters, this expert comparison clarifies their distinct roles and maintenance needs.
How an Automobile Converter Works
As hot exhaust enters the front face of the automobile converter, gases spread through the thousands of minuscule channels in the substrate. The large surface area means that even at high engine loads each molecule has ample exposure to the catalytic wash-coat. Oxidation converts carbon monoxide and unburnt hydrocarbons into carbon dioxide and water, while reduction converts nitrogen oxides back into harmless nitrogen. Integrated oxygen sensors relay real-time data to the engine-management system, allowing the ECU to maintain the optimal stoichiometric ratio for the automobile converter to perform at peak efficiency. Curious about the substrate itself? Read how a monolithic honeycomb design maximises surface area in this in-depth monolith overview.

How to Identify a Failing Automobile Converter
Recognising the early signs of a failing automobile converter can save you from breakdowns and expensive engine repairs. Typical symptoms include a rotten-egg smell, sluggish acceleration, and an illuminated check-engine light displaying P0420 or P0430 codes. In severe cases the automobile-converter substrate melts and creates a physical blockage, causing the exhaust system to glow red-hot. If you notice any of these warning signs, call Catman on 01489 666 384 or email info@catman.co.uk for a free diagnostic consultation.
Another red flag is a rattling noise coming from beneath the car. This occurs when the internal matrix of the automobile converter breaks apart after severe thermal shock or impact damage. Fuel contamination—often triggered by a misfiring spark plug or leaky injector—can also poison the precious metals, rendering the automobile converter ineffective. For marque-specific troubleshooting, read our guides on Honda and Volkswagen converter issues. For additional technical checks before mounting any new unit, consult this essential installation checklist.
Step-by-Step Automobile Converter Installation Guide
Although many customers prefer professional installation, mechanically minded drivers can replace an automobile converter in their own workshop by following Catman’s detailed guide below. Always ensure your workspace is well-ventilated and that the exhaust system is cool to the touch.
- Preparation: Gather a new automobile converter, gaskets, anti-seize compound, jack stands, O₂-sensor socket, and torque wrench.
- Lift and secure: Elevate the vehicle on stands, ensuring the wheels are chocked and the handbrake is applied. Never work beneath an unsupported car.
- Remove sensors: Disconnect any oxygen sensors ahead of the automobile converter to prevent wire strain.
- Loosen fasteners: Spray penetrating oil on rusty bolts and allow a 10-minute soak before removal.
- Detach the old unit: Support the exhaust with a second jack, unbolt the flanges, and slide out the failed automobile converter.
- Compare parts: Verify that the new Catman-supplied automobile converter matches length, port alignment, and hanger positions.
- Install gaskets: Fit new graphite or metal gaskets between mating surfaces to create a gas-tight seal.
- Mount the new converter: Position the automobile converter, finger-tighten all hardware, then torque to manufacturer specs.
- Reconnect sensors: Apply a dab of anti-seize to the O₂ threads and reinstall the sensors.
- Final checks: Start the engine, listen for exhaust leaks, and monitor live O₂ readings to confirm the automobile converter is online.
Maintaining Your Automobile Converter for Long-Term Performance
Proper maintenance extends the life of any automobile converter and keeps operating costs down. Follow these Catman-approved best practices:
- Stay on top of tune-ups: Ignition misfires send raw fuel into the automobile converter, overheating the catalyst.
- Use quality fuel and additives: Lower-sulphur, detergent-enhanced petrol or diesel keeps the automobile-converter substrate free from sulphuric-acid build-up.
- Resolve engine warnings quickly: Prolonged operation with fault codes can clog the automobile converter and DPF.
- Schedule periodic back-pressure tests: Catman partners with nationwide garages that can measure how freely gases pass through your automobile converter.
- Clean associated filters: For diesel vehicles, regular DPF regeneration complements a healthy automobile converter. Learn how in our Skoda Octavia DPF regeneration guide and deepen your understanding with this detailed DPF vs. catalytic converter explainer.
