SPI Short Header Installation 

1. Disconnect the battery negative ground lead. 2. Remove the two bolts mounting the power steering line to the heat shield. 3. Remove the heat shield. 4. Disconnect the wire plug from the oxygen sensor (it is bright green and above the radiator). 5. Unbolt the stock header from the engine and the two bolts connecting the header to the right side mount. 6. Unbolt the four bolts holding the header to the cat. 7. Get under the car and remove the two bolts that mount the cat to the car. You should be prepared for it to fall. Make sure to go slow when lowering it. There is a sensor connected to it, and you don’t want that to pop out. (I held it up with my tool box).
 

8. Return to the engine compartment and lift the stock header out.
 

9. Use a 3M finishing pad to clean off the old gasket from the engine. 10. Use an adjustable wrench to remove the oxygen sensor and a socket wrench to remove the two metal pieces from the stock header. 11. Install the oxygen sensor and the two metal pieces onto the new header.
 

12. With the cat still lowered, install new gaskets and bolt the new header onto the cat. 13. Lift the entire thing up and slide the two metal pieces into their mounting places. 14. Bolt the cat back onto the car. 15. Return to the engine compartment and bolt the header to the engine. 16. Re-plug in the oxygen sensor. 17. Flip the power steering mounting bracket 180 degrees so that it’s pointing towards you. Pull it forward and mark off where it touches the mounting for the radiator. Move it out of the way and then drill two holes where you marked. Use self-tapping bolts to mount the power steering line there.
 

18. Double check all bolts to make sure they are as tight as possible. 19. Re-connect the battery. 20. Start the car and check for leaks. If there are any, make sure all bolts are tightened to torque spec (123 ft/lb) and that you replaced the old gaskets. If not, close the hood and enjoy!
