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

  3. Before moving on, check over all of your gaskets and make sure they are in good condition.

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!
