Sports CAT
#2
You may need to increase the size of the restrictor in the hose from the turbo outlet nipple to the wastegate actuator, to control the overboost you'll invariably get from having the free-er flowing downpipe. I have the full 3 inch GGR sports cat exhaust, and it is a nice piece of kit. Only criticism is the tailpipe sticks out a bit too far.
