is this normal?

i was just wondering if it is normal for x pipes to bump around or vibrate roughly. i got my pypes performance xpipe and mufflers installed today, love the sound its sooooo loud. but was wondering about the knocking and vibrating. if its not normal what do i do to fix this?

You shouldn't have any vibration or knocking around after the install. Sounds like something may be loose. I'de check it for exhuast leaks and make sure nothing is loose. If nothing is loose and if everything is installed correctly, then it is most likely one of two other things. One, something else on the car has come loose and is knocking around. Two, the "x" position of the x-pipe "may" be making contact with the driveshaft when going over hills and bumps. This can sometimes occur.
