Basic Installation instructions:

1) This header was designed to be installed from underneath the car, requiring the removal of the stock manifold, down pipe, cross member and power steering bracket. You will need to jack the car high enough (or use a car lift) to slide the header under the car and lift it into place. Be sure to let the car cool down COMPLETELY before attempting to work anywhere near the exhaust system.

2) Start by disconnecting the battery ( you will be working near the alternator), and spraying all nuts with rust buster. Let it soak at least 1/2 hour or you WILL break something.

3) Remove stock manifolds and down pipe. Disconnect and label O2 sensors (front manifold, rear manifold, etc. ) The rear header is easier to remove if you take it apart.

4) Remove power steering bracket for removal of manifold, and donŐt re-install it or it will rattle on the headers.

5) Install headers, and put on nuts finger tight only. Leave ALL nuts loose. You can re-use the stock gaskets.

6) Line up Y-pipe with 2 headers and cat. Converter before attempting to install it. Once everything is close, start by installing the front gasket and 3 bolts (leave them loose) then the rear. Only bolt the y-pipe to the converter after the headers are located correctly on the y-pipe. Be sure to use the new cat gasket.

7) Tighten all nuts evenly, starting with the headers and working down. .

8) Extend O2 sensor wires using supplied kit. Be sure to cut and splice wires one by one to make sure y9ou do not get them mixed up. Install O2 sensor into fitting and tighten securely. You will need to have the 2 supplied O2 bungs welded into your exhaust system AFTER the cat in order to NOT get a CEL (Check Engine Light).

9) Check for loose connectors, and re-connect battery

10) Before starting car for first time, wipe header down with mild solution of soap and water to remove any grease or fingerprints.

11) Lower car and start. Check for leaks. A leak will sound like a steady sputtering, and you will be able to feel pulses of exhaust. If you do not feel any exhaust pulses, and you think you have a leak, it is probably just the difference in sound form the stock manifold compared to the race header.
