ISR Performance Long tube headers for Nissan 370Z and G37 with VQ37 

The 370Z ISR Long Tube headers for are designed to replace your factory headers and catalytic converter. These long tube headers are constructed with 304 brushes stainless steel and heavy duty flanges. Designed with a stepped primary, these headers are built to retain as much low and mid range torque as possible while allowing for good top end horsepower gains as well.

The innovative High Ground Clearance, "HGC" design places the collector in a position to maximize ground clearance without sacrificing performance.

Each header features 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors. The downstream o2 sensor bung utilizes a flow restrictor to help avoid CELs.

You will be required to extend your primary o2 sensor harness to meet the new location which is lower on the header. 

With an UpRev Tune, Intake, Headers and full exhaust you can expect a +40whp/23wtq gain
