While further developing the naturally aspirated route of the 350Z and G35 we found the stock cats to be extremely restrictive.

In our redesign, we removed the secondary factory cats and replaced the primary with far more free-flowing converters.

Added torque should be expected as well as a slightly more aggressive exhaust note.

These are the perfect complement to our headers.

Our high flow cats come with all hardware required for installtion on any stock or aftermarket exhaust system, and with bungs installed for use with the factory oxygen sensors.
