Cmon Guys, Help Me out Here... Is This NORMAL????

I just put on a new Dynomax exhaust and a high flow cat. I also replaced the 2 O2 sensors. since putting the exhaust on, I've noticed that the engine takes longer to shift inbetween gears and instead of kicking down a gear when I needed a little bit of acceleration, it stays in gear. The power is deffinetly there if I would floor it but it seems to cause power loss in normal driving copared to how it was before. Thanks for any advice! Also- its a '97 4.0 with AW4.
