3. O2 sensor bungs (if used) can be positioned on the header collector where the sensor wires can be routed away from hot
engine components (O2 sensor wire extensions are provided). Drill 3/4” hole and weld bung to collector.
4. EGR sub-assembly provisions (if needed) can be installed by attaching the vehicles EGR flange to the sub-assembly provided
(Two sub-assemblies have been provided. Choose the one that fits your car best). Trim the provided sub-assembly tube.
Mark and drill the header primary tube with a 1/2” drill. Weld sub-assembly to header tube.
5. A.I.R. sub-assemblies provisions (if needed) can be installed by attaching the vehicle’s A.I.R. flange to the provided A.I.R. sub-
assembly. Trim the tubes, mark and drill 1/2” diameter holes and weld to primary tube.

the tube, it creates a low
pressure area on the backside,
which translate into vacuum.
