High Flow Cats, Metallic Substrate, Dual 60mm Pipes

The Berk Technology High Flow Cats (BT1401-HFC-MET) are engineered to significantly improve exhaust flow and unleash hidden potential in your vehicle. Constructed with a full 304 stainless steel construction, these catalytic converters feature dual 60mm piping and a metallic substrate, offering higher flow and lighter weight compared to factory components. The advanced spiral-wound, ultra-thin foil design makes them particularly well-suited for forced induction applications. Designed as a direct replacement, these high-flow cats are compatible with the Nissan 350Z (2003-2006) and Infiniti G35 (Coupe 2003-2007, Sedan 2003-2006) models equipped with the VQ35DE engine. They are also compatible with automatic transmissions and can work with various aftermarket exhaust systems like HKS. While they will make the exhaust slightly louder than stock, they are not as loud as resonated test pipes. These catalytic converters are OBDII and 49-state compliant, and include a built-in O2 CEL fix to prevent check engine lights. Made in the USA, they offer a significant cost savings over OEM replacement parts while providing a performance upgrade. Installation is described as straightforward.
