Universal catalysts

Car catalytic converter is responsible for cleaning the exhaust gases of harmful compounds produced by the combustion of the fuel-air mixture. It usually occurs just after the turbocharger in the case of turbocharged cars and directly after the exhaust manifold in the case of naturally aspirated cars. The location of the catalytic converter is not accidental, because the higher the temperature of the exhaust gas, the greater the effectiveness of the catalytic converter.

We offer catalytic converters with either a ceramic or metal core.

Catalytic converters with ceramic inserts are usually found originally in catalytic converters installed in series in factories, but sometimes there are also metal inserts, although very rarely. Ceramic inserts are less resistant to the higher combustion temperatures that occur in cars with a gas system installed. Manufacturers usually do not even give a warranty when installing such a catalytic converter for this type of car. There are also catalytic converters with a metal insert ( core ). These can confidently be used in cars with gas installation installed, and those with increased capacity also with a metal insert are great for tuning. Most of the catalytic converters in our offer have metal inserts.

When it comes to choosing the right catalytic converter in relation to the capacity and power of a given car, the principle of selecting a catalytic converter according to the engine capacity is applied, and so for a car with an engine capacity of 1.8 suitable, will be the one in the range of 1.6-2.0. For cars with a 2.0 engine with a capacity of less than 150 horses will be suitable in the range of 1.6-2.0, but already for a car with a capacity of more than 150 horses will be suitable in the range of 2.0-3.0 liters of capacity. In addition, usually in cars equipped with v6 or v8 engines or where the exhaust of the cylinders is split in half, the principle of parallel mounting applies, which is that two catalytic converters of 1.6-2.0 liters are able to handle cars of 3.2-4.0 liters.

On the subject of the intricacies of catalytic converter throughput, which is 400-600 cpsi as standard, here is a more detailed distinction:

Catalytic converters in gasoline cars with Euro 2, Euro 3 and Euro 4 emission standards usually have a throughput of 400 cpsi, Sometimes in Euro 4 there is 500 cpsi. However, for Euro 5 the standard throughput is 500-600 cpsi, for Euro 6 it is 600 cpsi.

Slightly different is the situation in cars with diesel engines. The standard capacity for Euro 2, Euro 3 and Euro 4 is 200 cpsi ( incidentally, such capacity is found in catalytic converters designed for cars with gasoline engines ). For Euro 5 and Euro 6 diesel standards, the standard throughput is 400 cpsi.

Under the rules for the application of emission standards according to the directives, it should be remembered, however, that some manufacturers introduced higher standards even before the effective date, and it is very common that cars from Japanese manufacturers and brands such as BMW and Merceses used catalytic converters with Euro 4 standards already in cars produced after 2000. It is best to check this in the documents that came with the vehicle, ask at the service center or use the appropriate program to decipher the VIN number. We, too, are happy to assist in selecting the right catalytic converter, feel free to contact us. This is also slightly different for diesel cars, there are subtle differences in years of use, so it is best to check well before buying.

- EURO 2 Directive 94/12/EC, 96/69/EC for passenger cars, in effect since 1996

- EURO 3 Directive 98/69/EC [12] for all vehicles, in effect since 2000

- EURO 4 Directive 98/69/EC, 2002/80/EC for all vehicles, in effect since 2005.

- EURO 5 Directive 2007/715/EC[13] for light passenger and company cars. In force since 2009.

- EURO 6 Commission Regulation (EU) No. 459/2012. In force since 2014.

The most common catalytic converter diameter is 110 -120 mm, length about 250 mm.

Most of the catalytic converters in our offer are made of s304 stainless steel and have a mounting diameter of 63.5 mm ( 60 mm inside ).

If you need a larger diameter you just need to cut the tapered bottom of the catalytic converter thus increasing the mounting diameter. If you need a smaller diameter you need to weld a piece of extruded tube so called "cone". We have various diameters of cones in our offer - link.

In cheaper catalytic converters with extruded catalytic converter box design, mounting diameters of 50 or 55 mm are available.

Do you need a different catalytic converter input/output diameter?

If you want a diameter larger than 63.5 mm then just cut the catalytic converter cone in the right one to the desired diameter and if 63.5 mm diameter is too large for the Shadow then you can get the reductions available in the link below:
