Help with Backfiring!

Hey guys, my car has been back firing real bad every time I step on it. Been happening about a week now and I have no clue what the problem could be, any suggestions? Thanks for your time

There must be some codes, hidden away, in the "magic box".
Have an auto parts store scan the codes, and post what they are...

Check your exhaust for holes. I had flowmasters that had rust holes in them and it would pop when i let off the gas. Put new mufflers on and no pop.

All depends on where you live. No rain snow salt you'll be fine. Or if to never drive in those conditions.

Hey guys sorry for the late reply but I found out why it was back firing so bad it was something so simple. Thefuel filter, it has never been changed but it still pops just a little around 5k any tips on why? Maybe ignition system? Plugs/wires?
