Description

The ISR Performance HGC Long Tube Headers are a performance exhaust component crafted from durable 304 brushed stainless steel with heavy-duty flanges for longevity. These headers are engineered with a stepped primary tube design, featuring 1-3/4" primaries and two O2 bungs for sensor integration. Designed as a direct replacement for the factory exhaust manifold and catalytic converter, these headers aim to optimize exhaust flow. They are intended for vehicles equipped with VQ35DE or VQ35HR engines. Fitment has been reported for Nissan 350Z (Z33), Infiniti G35, and customers have installed them on the 370z and G37 models. They are compatible with both AWD and RWD configurations and LHD and RHD vehicles, provided they utilize a VQ engine. An O2 extension harness may be required for proper installation on certain models.
