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. 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). Stainless steel monoliths withstand extreme vibration and temperatures that normally would destroy standard ceramic substrates. The result is a more durable and longer lasting converter.

100 Cell – Less restrictive, normally for track use only. 
200 Cell – Normally for road use to meet emissions requirements.
