Um... congratulations?

Kind of an odd first post there, but hey, no problem. Welcome to the forums!

Popping could be a whole slew of things, so unless you know how to look for and repair them, perhaps it's best to take it to a shop and have it looked at.

The things off the top of my head are: Loose/bad transmission mount, bad CV joint(s) in the drive shaft, yoke issues either end, flywheel issue of some sort, bent something or another, internal transmission issues...

Need more info, but again, this might be better taken up with some experts, like a dealership.

Wait, I misread your last post. Will revisit this in a little bit.

Edit: back.

So... There's several causes of this. Could be somewhat normal, in that back pressure relief and fuel cut off as the throttle is closed is one cause.

Too much unburnt fuel in the exhaust is another, although at WOT acceleration, sometimes that might happen.

Bent/stuck valves is a third, but I'm guessin' it's not that.

Bad timing is possible, but again... probably not.

If it's a leaky injector, you'd probably get an engine code on that. Have you had the codes pulled?

Have you done any exhaust changes? Sometimes different exhausts (see the back pressure thing) will cause that to sound louder, but it's normal.

Probably need an audio or a video of the symptom to try any further, but I'd say maybe you need to go to a shop if it's worrisome.
