yeah crack does kill. its far from silent at idle in person. it sounds low when your not really in the throttle but once your at quarter throttle its loud. it has the cat and the resonator. i bought the magnaflow catback and it wasnt loud enough for me so i pulled of the magnaflow mufflers and added pipe. so its got the factory cat, the magnaflow resonator and piping and tips from the catback kit but with no mufflers. i honestly regret spending the money on the magnaflow. but ill be probably putting the mufflers back on once my headers are on cause its going to be insanely loud with headers and no mufflers. oh and cully heres some pics of a guy on my other forum with a red one with black bowties but there painted not overlays.
