Congratulations on your purchase of the COBB Tuning Subaru SS WRX/STO/FXT 3" Downpipe! The following instructions will assist you through the installation process. Please read them BEFORE beginning the install to familiarize yourself with the steps and tools needed. If you feel you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.
IMPORTANT! Installing this kit will require custom tuning or utilizing an appropriate Stage Power Package map if you have a matching mechanical configuration. Please consult with COBB or an authorized ProTuner in your area if you have any questions!
If you'd like, at this time you can modify the factory heat shield in order to get it to fit with the COBB Downpipe. In order to do so cut off the lower portion of the heatshield along the lines dictated below.
The COBB Downpipe replaces both of the catalytic converter sections after the turbo with a one piece unit.
