High Flow Catalytic Converter CC41044 – 2.25" 57mm Euro 4 400 CPI

CC41044 high-flow catalytic converter is a universal-fit catalytic converter designed for custom exhaust fabrication and replacement applications requiring a 57mm (2.25") inlet and outlet.

Featuring a 400 CPI ceramic substrate and Euro 4 rating, CC70044 provides a balance between exhaust gas flow and emissions conversion. Its compact 115mm (4.5") body diameter makes it suitable for many applications where space is limited and a weld-in catalytic converter is required.

What Does 400 CPI Mean?

CPI means Cells Per Square Inch and refers to the density of the catalytic converter substrate. A 400 CPI ceramic substrate contains 400 small exhaust gas passages per square inch. This provides a larger catalytic surface area than lower-cell-density performance converters while still allowing good exhaust gas flow for street and replacement applications.

Important Emissions Information

Fitment Notes

• This is a universal weld-in catalytic converter and is not supplied as a vehicle-specific direct-fit assembly.
• Welding and exhaust fabrication are required.
• Confirm the exhaust pipe diameter before ordering.
• The inlet and outlet are both 51mm (2").
• No oxygen sensor fitting is incorporated into the converter body.
• If an oxygen sensor fitting is required, an appropriate sensor boss must be fitted separately in the correct position.
• Confirm available underbody clearance against the 115mm body diameter.
• Professional installation by an experienced exhaust workshop is recommended.

Why Catalytic Converters Fail

Premature catalytic converter failure can be caused by engine misfires, excessively rich fuel mixtures, oil consumption, coolant contamination, engine overheating and other engine or fuel-system faults. The cause of the original catalytic converter failure should be diagnosed and rectified before installing a replacement converter.

What’s Included

Frequently Asked Questions

What size exhaust does CC41044 suit?
CC70044 has a 57mm (2.25") inlet and 57mm (2.25") outlet.

Is CC41044 a direct-fit catalytic converter?
No. CC41044 is a universal weld-in catalytic converter, so welding and exhaust fabrication are required.

What substrate does it use?
CC41044 uses a 400 CPI ceramic substrate.

Does it have an oxygen sensor fitting?
No. There is no oxygen sensor boss fitted to the converter. If one is required, it must be installed separately in the appropriate exhaust position.

Is this catalytic converter Euro 4 rated?
Yes. CC1044 is rated to Euro 4. However, vehicle emissions performance depends on the complete engine and exhaust system, so a Euro 4 rating does not guarantee that every vehicle will pass a specific emissions test.

Would a Euro 5 converter be better for an emissions test?
Potentially, yes. Where emissions-test performance is a priority, a suitable Euro 5 400 CPI catalytic converter may provide a better option depending on the vehicle and application.

Can I pick up from the store?
Yes. Pick up is available but must be pre-arranged before collection.

How much is freight?
Freight varies depending on your delivery location and where stock is available. Please contact us for freight charges before ordering. Where possible, we can arrange dispatch from the nearest available product location to help reduce freight costs and delivery times.

Do you ship to the USA?
Yes. Best Mufflers regularly ships exhaust systems and exhaust parts to customers throughout the United States.

Please note that import duties, tariffs, taxes, and customs clearance fees are not included in the product or shipping price. Once your order is processed and the applicable charges are calculated, we will send you a secure payment link to finalise the import duties and tariff charges before dispatch.
