Product Description
The ISR Performance Long Tube headers for Nissan VQ35DE / VQ35HR are designed to replace your factory header 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 2x 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.
