G30 B58 540i Muffler Delete Installed

Before this I did a resonator delete and the sound had a good tone to it but not enough volume so I decided to take the risk of removing my mufflers. I removed the muffler from my 540i today and put my resonator back on. First impressions: The right exhaust tip started rattling upon startup which was not there before. The sound is vastly louder from outside and in the cabin. I was expecting pops and bangs but they did not occur even in sport mode. There is drone present between 1.5-2.5k rpm but is not terrible. The car is almost as quiet as stock when off throttle or under light load. The real difference is when accelerating over 3k. The sound is amazing! It is very fierce now with a rip through the upshifts and occasional burbles on downshifts. I hope that the muffler delete develops pops and bangs over time as that is the only thing missing from the soundtrack. Overall, I'd recommend doing it if you don't mind a bit of drone.

If you are looking for pops and bangs than install MHD stage 1/2 with burble settings on (I have mine set on OEM power and 0,7s long).... Are you driving in Sport+ Mode?

It is hard to rate this sound.

I have had bootmod3 for a week and the sound is completely different. If anyone is thinking about getting it for their 540 I recommend it 100% I will get a better sound clip and post on here.

The problem in the 540i isn't so much the resonator/muffler as it is the downpipe. The downpipe on this car absolutely kills the sound and chokes the engine.
I installed a catless downpipe on mine along with the MPPSK kit, sounds fantastic! Planning to do a resonator delete to make it even louder haha
