Do us all a favor and dyno the car instead of posting a sound clip.
I personally picked up 13 hp and 4 ftlbs torque from the addition of cats and Y-pipe. Every car is different, but my Vette usually picked up 5-6 hp on the top end from aftermaket cats vs straight pipes. Also post your fuel/air as mine improved a great deal below 5000 rpm but still stayed around 12 to 1 over that rpm. Typically you see the free flowing effect more at higher rpm were more cfm is flowed.
