300-Cell Metallic Substrate Cat-Back Exhaust

The ISR Performance High Flow Cat Pipes offer an upgrade for your Nissan 370Z (2009-2020) and Infiniti G37 (2008-2013) equipped with VQ35HR or VQ37VHR engines. They are also compatible with the 2007-2008 Nissan 350z models featuring the VQ35HR engine. Constructed with a 300-cell spun metallic substrate, these high-flow cats are designed to reduce exhaust restriction, potentially leading to power gains. The pipes feature true mandrel bends for optimal flow and are fully TIG welded for durability. The design retains the factory oxygen sensor locations, ensuring seamless integration with your existing sensor setup. However, please note that these cat pipes are not compatible with DE style shorty header swaps and will not fit convertible models. They are compatible with vehicles that have OEM HR/VHR headers.
