Muffler delete - experiences (?)

Hi guys,

I'm about doing a muffler delete and resonator delete on the M240i.
But - today I've been as a passanger in a 335i (E92 pre-LCI) N54 (I guess) with just a muffler delete. And I was about to have a head-ache! Guys, even a floor was vibrating during the acceleration. It was a f*cking crazy. I don't understand that. I'm young I can handle loud things but holy crap, this was just too much.

Has anyone simmilar experiences with deleting muffler on the B58? Or is it more quiete on the M240i/340i? I don't want to have this on my car. Everything was vibrating in that 335i during acceleration.

I had it done 2 days ago. Very impressed with results. Sounds incredible. Going to get the resonators out too in a week or so. There is no vibration like you described in the 335i.

I'll try and get you a video (just muffler delete). For now, I can tell you that after 3.5k revs the engine just sings and fills the surrounding space. It's not obnoxious tho.

depends on the person, i personally do not like the sound of muffler delete on daily drivers. I recommend you listen to one in person before doing it.

It also drones inside the cabin at certain RPM
