Just a little feedback for everyone. Just installed the C&L... The stang seems to pull harder with less throttle. However, I didn't really feel too much "seat of pants" improvement. I, however, never do unless it's something really major. Like all things, I would feel it if i took it off. Install was a piece of cake and I did it in 20 min w/ my g/f handing me bolts (only used 8mm and 10mm socket). I did, however, have to rig one of the vaccume lines (the one at the back) because it was the wrong size. My g/f's fault, though, she ordered it for a 96 when i have 01 top end... didn't think it would mess up that but it sure did. Oh well, never EVER do an install without some sort of trouble.
