Default wierd idle...

After putting on my new exhaust ive noticed a wierd phenomenon...After driving around and then sitting and idling at a red light or whatever, the rpms bob down a couple of times like the cars gonna die and then level out. This only happens randomly, but it is a frequent occurence. I just had my battery and alt checked and everythign electrical is fine. What do you think is wrong????
