exhaust question

[96240SX41]

Hey yall. . .i've got a question, but before i ask i will tell you what has been done to the exhaust ok. . ok-

Hotshot header (4-2-1)

straight pipe with a pretty small resonator

All the way to a Magnaflow dual outlet muffler

Now, question, everytime i let off the gas, it lets out little pops. The popping only happens when i've have gunned it around. . .but when i'm just cruising (driving normal) it won't do it. I've done the whole "tune-up", i've put magnacore 8.8 wires, bosch platinum 2, oil change, etc.How can i get rid of this guys?

thats just minor backfiring from having an extremely free flowing exhaust, my mazda did the same thing, i thought it sounded kinda sexy.

only thing that might tone it down would be to get a bigger resonator
