Features:

The ISR Performance Long Tube headers for VQ35DE/HR are designed to replace your factory header. These long tube headers are constructed with 304 brushed 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 two o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors.

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

What’s in the Box:

• 2x Stainless Steel Long Tube Headers
  
• 2x 2 bolt exhaust gaskets
• 2x Head to manifold gaskets
  
• 4x o2 sensor bung plugs

Note: ***PLEASE INSPECT YOUR HARNESS PRIOR TO ORDERING AND ENSURE YOU HAVE THE EARLY MODEL VQ35DE 4 WIRE O2 SENSORS IN PLACE, THIS WILL NOT WORK WITH LATER MODEL 6 WIRE O2 SENSORS!***
