Description

The ISR Performance HGC Long Tube Headers are crafted from durable 304 brushed stainless steel, featuring heavy-duty flanges for robust construction. The innovative High Ground Clearance (HGC) design strategically places the collector to offer maximum clearance without compromising performance. Each header is equipped with two O2 bungs located downstream of the collector, allowing for the use of your factory upstream and downstream O2 sensors. It is important to note that you will need to extend your primary O2 sensor harness to reach the new, lower location on the header. These headers are designed for the Nissan Z33 350Z (2003-2009) and Z34 370Z (2009-2021).
