Tools Needed


Stock Exhaust Removal


Note

Before beginning it may be useful to spray down all of your exhaust bolts and the O2 sensor with penetrating oil to allow it to come out more easily.  This is particularly more important if your vehicle is older or has higher mileage.


  1. Jack your car up in a flat level area.  Allow it to cool down.

  2. Up top, unplug your front oxygen sensor connector.

  3. Behind the passenger's side wheel (USDM) undo the two trim clips and slide the access cover out of the way.

        


  4. Now using your 22mm oxygen sensor socket, remove the O2 sensor from the manifold.

  5. Remove the 4 12mm bolts holding the heat shield in place on the manifold.




  6. Remove the two 14mm nut and bolt combinations holding the uppipe to the manifold.




  7. Remove the three 14mm nuts holding the manifold to the head.

COBB Uppipe Install

  1. With the gasket in place, slip the up-pipe into place from the bottom, you can sometimes get it to stay in place, but it will help to have a friend to get a nut in place to hold it up.

  2. Apply a small amount of anti-seize to the threads of each fastener before installation.

  3. Install the manifold and loosely bolt it down to the manifold, crossover pipe, and uppipe making sure to install gaskets as you go.

  4. Once everything but the downpipe is in, go through starting from the cylinder head and torque everything down to factory Specs.

  5. With those tightened up, fit the downpipe in place and torque down to the exhaust.

  6. Re-install the top mount intercooler making sure everything is seated appropriately to avoid leaks.

  7. Flash a tune for your new Uppipe

  8. Go out and enjoy!
