These are my exact directions.
1. Disconnect battery. Raise vehicle using lift or jack stands. Do not go under vehicle using only the service jack. Let vehicle cool.
2. Remove heat shield and 02 sensor at wire connection. Remoce 02 sensor from manifold after manifold is off engine.
3. Unbolt manifold at collector. Support converter and floor stand. Unbolt maifold and remove from top.
4. Cut inlet pipe to converter at weld on the inlet side of the converter. Grind weld and remove inlet pipe from inside converter inlet. Deburr converter inlet.
5. Clean all gasket surfaces and install new gaskets provided in the kit. A supplemental gasket sealer such as ULTRA COOPER is recommended.
6.Remove 02 sensor from factory manifold and install in header. Slip header into place from above and bolt header to engine reusing factory hardware. Torque to 30-35 ft lbs, starting in the center and progressively working to outside.
7. Using bolts, washers, compression springs and nuts, bolt extension pipe to header.
8. Slip extension pipe into converter inlet. Position system to orginal location and TACK WELD extension pipe to converter inlet. Loosen ball pivot bolts and drop converter fro welding access. Weld extension to converter and reconnect ball pivot joint. Tighten spring bolts.
