![]() ![]() Since 1992 all production cars in the UK had to have a catalyst fitted. If the vehicle is to be used on the road, a 200 cell catalyst is necessary. 100 cell catalysts are the least restrictive and ensure track compliance. ![]() All FiA converters are supplied as complete working units and ready to be welded to pipework. For FiA championships, an FiA approved 100 cell catalyst has to be used an example can be seen here. As road emissions regulations are not an issue, a 100 cell catalyst can be used. Most track meets whether FiA or non-FiA require that a catalyst of some sort is fitted. Off road/track use? (usually use 100 cell) Once you know what your application requires, the catalyst will do the hard work. There are different cell structures, mantle sizes, end cones, pipe diameters, BHP and emission ratings to deal with. Understanding which catalyst to use requires a few questions to be answered to narrow your choice down. ![]() Please note that is is illegal to fit a non-type approved catalyst (universal catalyst) to a road-going vehicle first used on or after, as per The Motor Vehicles (Replacement of Catalytic Converters and Pollution Control Devices) Regulations 2009. For road cars we recommend a 200 cell catalyst for emissions compliance (for cars up to March 1st 2001). Some cars are used for both and therefore sometimes a 200 cell is necessary. For off-road or track use we recommend a 100 cell catalyst. Our catalysts can be supplied as complete units for welding (or clamping – depending on the type of catalyst) or as components for the customer to create their own catalyst. The result is a more durable and longer lasting converter. Stainless steel monoliths withstand extreme vibration and temperatures that normally would destroy standard ceramic substrates. This is achieved by a using a lower density stainless steel monolith matrix: 100 or 200 cells per square inch (cpsi), when compared to a standard ceramic substrate (400 or 600 cpsi). Jetex offer a huge range of high flow, performance catalysts that are designed to reduce back pressure and increase engine power output through significantly increased exhaust gas flow over OEM and standard aftermarket converters.
