Custom Sports Catalysts
Jetex Performance Catalytic Converters are designed to reduce backpressure and increase engine power output through significantly increased exhaust gas flow over OEM and standard aftermarket converters. This is achieved by a using a lower density stainless steel monolith matrix: 100, 200 or 300 cells per square inch (cpsi) when compared to a standard ceramic substrate (400 or 600cpsi used on OEM or standard aftermarket converters).
The stainless steel monolith withstands extreme vibration and temperatures that can destroy standard ceramic substrates. The result is a more durable and longer lasting converter.
We can offer converters with 100 or 200cpsi, as complete units for welding or clamping, or as component parts for the customer to create their own sports catalyst.
For road cars we recommend a 200 cell catalyst for emissions compliance.
Please see our comprehensive list of converters below.
100cpsi FiA Approved Converters
4" or 5" versions available. Operate up to 1110 degrees, ideal for petrol sports cars and kit cars. Also available as a high temperature option (up to 1600 degrees) for higher powered or hot engines.
200cpsi Converters [Euro 2 (1996-2000)]
Suitable for older Euro 2 emission standard engines.
'X and Y' 200 Cell Converters
High flow oval catalysts, generally suitable for BMW and Mercedes applications.
Diesel Catalysts for 2.5" and 3" pipework
Suitable for diesel applications. Available as 100 or 200cpsi. Will reduce emissions but will not extract diesel particulates. Please use our highly effective universal DPF for particulate reduction.
Converters for Self-Assembly
100 or 200cpsi mantles (diameters of 4, 4.5 and 5”) should be used in conjunction with our cones for welding and/or stubs for clamping. Cones butt up to the mantle and can be TIG or MIG welded.
Designed to be welded to 4", 4.5" and 5" mantles. If used without stubs, the cones must be welded to the existing exhaust system.
To be used in conjunction with 4", 4.5" and 5" cones. Available to fit pipe diameters from 45mm to 76mm (1.75" to 3").
200cpsi E-marked Converters [Euro 3, 4 and 5 (2000-14)]
Suitable for road applications that require an EC approval. For any vehicle registered after 2001.
200cpsi Converters [Euro 5 (2009-14)]
Suitable for more modern engines with tighter emission controls from 2009 to 2014.
Oval 200cpsi Catalysts
A high flow, oval performance catalyst.
High Flow DPFs
Suitable as a replacement for an OEM DPF, our high flow DPFs increase gas flow, resulting in reduced back pressure of up to 50%, while maintaining a near parity in particulate extraction when compared to a standard DPF.
The unique dimpled spiral core combined with active surface molecules react with the exhaust gas when the DPF reaches 300 degrees. The particles are burnt off and so the DPF works continually, unlike a standard DPF which collects the particles and then has to enter regeneration mode, leading to loss of performance and inconvenience.
Suitable for Motorsport and Road Applications.
