From my 08 GT. Bought from Brenspeed. Serial starts with X3 so will not work with my '11 GT. Has the Brenspeed tunes plus the SCT canned tunes. 08 was put back to stock. Asking $250 paid $379. Has everything that came with it.
Guys have an '11 GT. Being in Rochester NY we must pass emission testing. What mods can be done and still pass emissions? Can you do exhaust work other than just a axle back?
