Catalytic converters are necessary to reduce emissions but create back pressure due to the exhaust gases being forced through a catalyst, and therefore decrease high end engine power. Many modern catalytic converters only produce 1-3 psi of back pressure, though this restriction worsens further with use. Hi-flow catalytic converters can replace the standard units in order to provide lower backpressure. Installing aftermarket catalytic converters is restricted by law in some states.

Companies that make a High Flow Catalytic Converters are Berk, MXP, Stillen & Kinetix.  Stay tuned for more upcoming companies to develop a high flow catalytic converter for the Infiniti G37.
