Nice little addition. I can't tell a sound difference but I was already pretty gurgly from the mid-pipe. Actually revving in N shows a little rasp. Not bad but hoping the break in of the cats will take some of that away. Nothing you notice from inside - wifee will never know....

As for power - hard to tell but the mid range seems to have more. All the mods seem to be about mid-range for me and I love this cars ability to roar at mid-rpm's. Crawford Rocks!
