Dual 60mm High Flow Catalytic Converters w/ O2 CEL Fix

The BERK Technology High Flow Cats (BT1407-HFC-MET) are engineered to enhance exhaust flow and performance for Nissan and Infiniti vehicles equipped with VQ35HR and VQ37VHR engines. Constructed from full 304 stainless steel, these catalytic converters feature dual 60mm high-flow metallic substrate elements, which offer improved flow and lighter weight compared to factory units. The metallic substrate uses an advanced spiral-wound, ultra-thin foil design. A key feature is the built-in O2 CEL (Check Engine Light) fix, which helps prevent illumination of the check engine light after installation. They are OBDII and 49-state compliant. Fitment includes Nissan 370Z (2009-up), 350Z (2007-2008), Infiniti G37 (2008-up), G35 Sedan (2007-up), Q40 (2015), Q50 (2014-2015), and Q60 (2014-2015). Importantly, these high-flow cats are not compatible with the 3.0t engine found in some Q50 models. The product is sold in pairs. Note that as of January 1st, 2009, performance high-flow cats are intended for off-road use only in California. Some sources mention these are compatible with AWD models.
