The ISR 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 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors.
