Could be a few things:

Pre-ignition in the headers (rich mixture/ raw fuel in the header)

sticking EGR valve, IAT, or emissions control valves

do you have a OBDII code checker, might be able to pin down the error.

Did you change the size of the piping? It could be due to lack of back pressure too. I've heard a few cars pop or gurgle after increasing the pipe size and adding a free flow muffler.

what? they are going to just turn you around and send you on your way with those kinds of mods. I too have hks dragger and when the rpm's drop from accelerating ther is a bit of backfire, kinda sounds cool. if its worth the time, go to a local shop and pay $20 to put the stock mufflers back then see what happens.

What you hear is normal because of the pre-muffler being removed ( assuming that is what you mean when you say "Silence REsonator Removed"). It should occur when you let off the gas for about 2-3 seconds and sound like a gurgling-sputtering popping. It is not a backfire but resonance of the volume of gas pressure decreasing to idle. Nearly all aftermarket exhausts do this if you remove the pre-silencer or get open mufflers.

ignition timing could be off... computer is supposed to "manage" that, but we all know how reliable computers are.

you sucker, I was talking on my own experience, I once had park ave acura install a simple intake on my car and curry acura ( a different dealer) refused to even attempt to solve an idle problem i was having blaming the possibility on the disassembly of the intake system. guess what, It was the problem and park ave took care of it. Just cuz your sore about your car, doesn't mean you can have an attitude. I'm not even going to take this any further, makes no sence to reason with such a hot head.
