If the header is to be used on for a race application, this Race Manifold Kit can be used to retain the use of emissions control system. The objective of this kit is to relocate the secondary oxygen sensor to a new position in the exhaust system directly behind the remaining catalytic converter. In order to accomplish this task, the factory connecting pipe must be removed from the vehicle and an oxygen sensor nut position must be drilled and a retaining nut welded in place.

This kit includes two (2) wiring harness extensions that are equipped with factory OEM style connector plugs, which eliminate the need to "cut and splice" the factory wiring harness. Teflon-coated 18-gauge wire is utilized to provide superior heat protection. Also supplied is an oxygen sensor mounting nut and detailed instructions.
