That is what ended up being my problem, you heard what mine sounded like before and the flame throwing, fixed it right up.

I also have Borla and mines been doing that (not horribly just once in a while) since I bought it and a little more so after headers. I’m not 100% sure but I would guess it’s from the stock pig rich tune. A new tune should fix it. (Correct me if I’m wrong guys) Try whats said above before you do this.

my car backfired a lot after i put my headers on and now that i got rid of my air injection it hasnt back fired at all since then and actually feels like it runs a lot better and my gas mileage has gone up a lot ... and also the engine bay looks a lot better

Just to chime in again, when mine popped at wot and on decel like a down shift or just letting it come down on it's own after wot w/out throwing it in neutral I though it was my tune aswell. We fully enabled the DFCO still didn't fix it. tried many other things and it ended up being the air pump like stated above in my first post. Actually it is the checkvalves in the lines going to the headers/manifolds. sounds like that is what fixed SiRgReg23's problem aswell. Not saying that will fix your problem for sure but it might.
So its prolly my AIR set up that usually gets deleted by most anyway? if so ill get it taken out when i do my other mods, if its not hurting my car or anyhting ill jsut wait. i jsut wanted to make sure my car wasnt going to blow up or somehting was wrong. lol thanks guys

Well when you let off the gas and it's coming down with ZERO throttle and it pops that would indicate a lean condition. That is what my Harley would do and my 4 wheeler, the proper jetting took care of that....which in these cases was a larger pilot jet.....so the proper tune will correct it for your car as well.
