Congratulations on your purchase of the COBB Tuning Subaru Catback. The following instructions will assist you through your installation process. Please read them first BEFORE beginning the install and familiarize yourself with the steps and tools needed. If you feel that you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.
Adding a small amount of anti-seize to the smaller, inside piece of each slip joint can help removing it in the future. Particularly because as you tighten down the clamps the pipe will typically deform slightly. |
Go through and make sure each of the slip fits over the otherand that the clamp is over the cut part of the pipe with some pipe remaining on the cut side. Once that is accomplished tighten down each section so that it is still movable but holds it's position so you can get things lined up. You'll need a 10mm socket for the smaller clamps and a 13mm for the large 3" on the mid-pipe to y-pipe.
