High-Flow Catalytic Converter Set

The Berks BT1407-HFC-MET High Flow Catalytic Converters are engineered to enhance exhaust flow and performance for compatible Nissan 370Z and Infiniti G37/G35/Q50/Q60 models with VQ35HR and VQ37VHR engines. Constructed from full stainless steel with a metallic substrate, these converters are lighter and offer improved flow compared to factory units. Featuring advanced spiral-wound, ultra-thin foil technology, they provide a high-flow solution without the "test pipe smell." The package includes custom-made soft crush graphite collector gaskets, as well as new front and rear gaskets, nuts, and bolts to ensure a complete and leak-free installation. These catalytic converters are made in the USA. Compatibility includes a range of models such as the 2007-2008 Infiniti G35 Sedan (VQ35HR), 2007-2008 Nissan 350Z Coupe/Convertible (VQ35HR), 2008-2013 Infiniti G37 Coupe/Convertible/Sedan (VQ37VHR), 2009-2019 Nissan 370Z Coupe/Convertible (VQ37VHR), and various Q50, Q60, and G25 models from 2011-2015 with relevant VQ engines. They are confirmed to fit AWD models. However, these converters will not fit the 3.0t engine found in some 2018 Q50 models. It is important to note that as of January 1st, 2009, performance high-flow cats are intended for off-road use only in the state of California. The product description also mentions that Berk no longer offers optional O2 sensor bungs as they were rarely used.
