Help with strange noise?

Hello everyone! Recently I've been hearing a low pitch "hollow" noise whenever I press the skinny pedal down. I just recently installed a VRSF catless downpipe so it may all just be in my head but it caught me off-guard. I'm in a '15 328i VRSF FMIC+DP, ER chargepipe and stage 2 93 tune. I'll try to attach videos below

It's feeling pretty great, especially after the TCU flash. I'm just concerned that there may be an exhaust leak

Ive heard a few dp bmws I dont really hear an issue with yours. Do not take my word for it though as I am not qualified to give advice on this matter...

When you went with DP did the car feel much faster?

Not necessarily faster but much better throttle response, the DP along with a Stage 2 tune really woke the car up

Odd, people who just do stage 1 say the car feels much faster. I am planning stage 1 very soon. Do you have an intercooler upgrade as well?

I mean yeah the car definitely pulls harder and feels way faster over stock lol if you're having doubts about going stage 1 don't worry, I did it completely stock and it was great...I would think about getting a chargepipe to handle the added boost if you're thinking about running any tune however

Yeah, I will be doing stage 1 and eventually getting a chargepipe. I hope my chargepipe doesnt break. I do still have a warranty so maybe I could relock the dme and get it fixed? Kinda scummy I guess. But yeah chargepipe will likely come with all my stage 2 mods.

The dealership can tell when the car has been flashed or piggybacked
