18gt mbrp race catback

[Oxford white 10r80 gt]

Today while cruising if I lightly stab the throttle in say 4th gear I get an exhaust flutter type noise into the cabin it sounds to be over the right muffler area I’m gonna jack it up tommorow any ideas on what to look for? I have had it on the car for quite some time and never noticed this noise till today. I tried to catch it on video with no luck starting to really look at Corsa Extreme but don’t wanna.

I’m not sure if drone is starting to make me hear different things in the cabin or what any help would be awesome

I will get pictures for you I was trying to avoid welding because I wanted to try something new I like the idea of clamps but it looks like that may be my option the sound plug was removed and plugged before I installed the catback I’m even having tip fitment issues it’s wanting to sit close to the valence I had it fixed at a shop but it’s like the tips have made their way right back to where they were before being adjusted lol talk about frustrating
