The Exhaust Headers are a direct replacement shorty style header manufactured out of 16 gage mild steel.
The installation of the header utilizes the use of the stock connecting pipes and does not require the
relocation of any sensor, except for Jeep models. Part #s that begin with "72C" are coated with a metallic—
ceramic compound.

The Exhaust Headers for the Jeep models are a long tube style header manufactured out of 16 gage mild
steel tubing. The location of the oxygen sensor is at the collector, similar to the stock configuration.
On vehicles where the existing oxygen sensor wire loom does not reach the new oxygen sensor location,
PaceSetter will provide a wire loom extension that will plug into the factory connector.
