These long tube headers are constructed from brushed 304 stainless steel with heavy duty flanges. These headers are built to retain as much low and mid range torque as possible while still allowing for high RPM horsepower gains.
The innovative High Ground Clearance, “HGC,” design places the collector in a position that maximizes ground clearance without sacrificing performance.

Each manifold has 2 o2 bungs placed downstream of the manifold so you can use your stock o2 sensors upstream and downstream.
You will need to extend your primary o2 sensor harness so it can fit in the new location which is lower on the manifold.

BOX CONTENTS:
-2 long stainless steel collectors
-2 x 2-bolt exhaust gaskets
-2 gaskets between the head and the collector
-4 o2 probe caps
-4 exhaust nuts
-4 exhaust bolts
