Please help me diagnose this noise whenever I lightly press the gas pedal!

Please if you can help me figure out what is going on with my car. Here is a link to the YouTube video that i uploaded.

This is the description in the YouTube video: Please help me try and diagnose what the problem might be. Whenever I lightly press the gas pedal it changes the exhaust note to a very deep gurgling noise and I have to press the gas pedal down a little more in order for it to stop making the noise. I’ve tried my best to catch the noise on my phone. Thank you to all those who can try and help me.

hard to hear.... is this car new to you? Sounds kind of like AFM kicking in? AFM sounds terrible with modified exhaust and it sounds like you may not even have mufflers? I dunno.

I have had this car for about 2 years and i have diverters opened so it would be some what easier to hear. I have tried replacing the coil packs nothing happened with that. I was thinking it was possibly the fuel injectors. Im not really sure haha.

sounds like afm or "lugging" (transmission in too high of a gear)

I wouldn’t suggest replacing the injectors for that noise.

Maybe someone else will chime in that can hear the noise better and direct you to a better diagnosis.

For now, I’d suggest you go over the basics like making sure your plug wires are all tight, oil is reading correctly and maybe look to see if any cats are discolored (or if they rattle when you tap them? ) or if you have an exhaust leak ?
