Part List
Tools Needed
Removing Factory Downpipe
Using an 8mm socket, remove the four (4) bolts holding the exhaust manifold heat shield to the car. The heat shield will be loose but difficult to remove, you’ll just need to push it aside later.
With a 10mm socket, using an extension and universal joint, reach down the back of the motor and locate the upper-most downpipe bolt that holds the downpipe to the turbo. Compare the mounting pattern to your COBB downpipe to get an idea of where you’ll need to reach. You’ll need to push the heat shield out of the way to gain access. Depending on your tools, you may also have access to the second bolt towards the passenger side of the flange.
Moving under the car, raise the car up on jack stands or on the lift. Using a 13mm socket, remove the four (4) nuts that hold the bracket that connects the downpipe to the transmission.
Reaching up with a 10mm socket or wrench (ratcheting if possible) remove the remaining bolt(s) that secure the downpipe to the turbo and remove the downpipe from the car. It may be tricky but you’ll get it.
