I replaced the stock mids with catless ones. I did notice more torque in the mid/upper rpm range but could be placebo. saves about 3-4 lbs per pipe. The big diff is the sound. pure raw signature flat 6 exhaust note. My experience may be specific tho as my prior mods were headers, catback, custom CAI, 997 plenum and tb on a 3.2.
