Your original catalytic converter will typically have 400 or 600 Cells per square inch (CPSI)? these original cats are restrictive in their flow? typically allowing an open area of around 55-65%

Milltek Sport Hi-Flow Sports Cat which will be fully integrated into a large bore downpipe? has only 100-200 CPSI depending on application

These cats have an open area of between 75-85%? thus reducing back pressure substantially and increasing flow rates? all very desirable for extracting more performance? especially on Turbo-Charged engines.

• Emission levels are maintained at legal limits by careful selection of the volume of the metallic substrate.
• Lamda probe positions remain unchanged from the original equipment.
• Manufactured from 304 aircraft grade stainless steel.

• MSFD213: Large Bore Downpipe & Hiflow Cat
