Possible Backfire...weird pop noise

From time to time when coming to a stop or to make a turn my truck sounds like it has a slight backfire or pop coming from the rear of the truck. Does not do it all the time and is hard to replicate, but have heard it a couple of times now. I have the SPD turbo adapters installed and just put in the Airaid drop in filter. Don’t remember hearing the sound prior to the filter install. I have put the stock filter back in to see if that rectifies the issue. No codes or CEL is coming on. No other engine, exhaust, or performance mods have been done.

Anyone have any thoughts? Could the combination of the adapters and filter cause this issue?

Is anyone else running the same set up with just a drop in filter and adapters.
