It's a flap on the muffler, common issue... You can remove it

so looking i seen there is a flap inside the right muffler, and after research its supposed to move but it wasnt moving had GF hit the gas up to 4k rpm and it never opened, little sledge hammer wouldnt budge it at first took lots of hits to get it open a tad got it almost open all the way and golf tee for the vacum line took care of that the car sounds way better and way more responsive not what i was looking for but it lead me to fix that issue. not really worried about idle quietness which is what that was for i guess. still need to see whats rattling when bass is hitting
