Reasons for backfiring

Hey guys/gals;
After few weeks of working on interior, I got to drive my truck last weekend but boy! it was backfired eack time I let the pedal go especially in downhill. It doesn't back fire when my foot is on the gas or when it idles. I have glass pack mufflers (I never had one before), can some of it related to them?
Does warmer weather has anything to do with this also? Sorry if the questions are not smart ones.
Thanks.
