Milltek Sport 1610192040 Hi-Flow Cat
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%.
A Milltek Sport Hi-flow Sports Cat, has only 100-200 cpsi
depending on application. Milltek Sport Hi-Flow 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 turbocharged engines. Emission levels
are maintained at legal limits by careful selection of the volume
of the metallic substrate. Oxygen Sensor positions remain unchanged
from the original equipment.
