OK, I have gotten dozens of pms over the last couple months regarding the muffler delete and "how does it sound...". So, I figured I would just take a few vids under different circumstances so you could get a decent representation how it sounds and hopefully, settle some of the confusion.

The car has the OEM headers, the OEM intake, both OEM resonators, and no muffler... just piping out the back to tips. Also has a vorsteiner dual sided hood if that makes any difference (maybe it's lighter so has less sound dampening :dunno: )

Anyways, here you go. I figured doing it at night would be best as you could see the speedometer and RPMs best.:

You didnt upset me but a real exhaust system will sound way better, Give HP rather than loosing it and dosent sound rice

The headers you would gain power from, More if they where equal length headers , But id doubt you made anything by removing the muffler

I drove my 330ci at various speeds between 50-90mph last night and there was barely any drone! Anyone who says the drone at highway speeds is unbearable, they must have super super hearing or something. It sounds amazing on the highway especially going under overpasses! Anyone looking at YouTube videos, just dont. They dont do justice to the real sound.

It'll sound like you're driving a race car all the time. No doubt it sounds good when you want to go for a blast on some twisty stuff, but it just sounds ridiculous around town. I have a friend with the same muffler delete, and driving 6 cars in front of him in traffic just makes it sound ridiculous.

I have the second resonator removed on my 325ci, now that is the best compromise imo. Only loud over 4000rpm, I'm even considering removing the other resonator now!

the car is extremely loud but for some reason it does not annoy me when i drive around town or anything. i guess its personal preference, i know many people that dont mind it and others that would never even conciser getting a muffler delete on that car. yea removing the second resonator would make it sound much better :thumbup:
