The 9-2x Aero??? They should be able to hit 13’s pretty easily with an intake, reflash and turboback 3" exhaust.
EDIT: 2006 and up are the best years for the 9-2x aero, thats when they switched to the 2.5 turbo motor instead of the 2.0 turbo. The 2.5T has only 3 more hp, but about 20 more ft/lbs of torque. The 2.5 responds better to mods from what i understand.
