Cold air intake and downpipe, done - more grunt, much better throttle response - cat back exhaust scheduled for Wednesday. Going with the AWE "Touring" exhaust.
Still debating the tunes - APR has a "plus" tune that adds about 50-60HP and 50-60 FP of torque (vs 80-100 hp and about 70FP on the stage 1), and, they cover any factory warranty issues that the mani may not. Hmmm.
