Just did this mod to my F31 340i because I really liked the sound of your car and got encouraged by it. On video it doesn´t even come close to how absurdly loud it is in reality. :D

[@kniffswelt]

Awesome, i agree the microphone can't pick up the sound.. it's way louder in real life 💥🤣

[@solimedia1379]

Do a flyby video please!

[@kniffswelt]

Will do!

[@Ufukk58]

Kannst du eine db messung machen mit geschlossener klappe?

[@Ufukk58]

Will mir auch sowas zulegen und möchte wissen ob ich in der db toleranz bleibe (bin aus Österreich) db toleranz ist bei uns +- 2db🙄

[@kniffswelt]

I can try, in comfort mode i think it's very similar to stock sound level

[@kniffswelt]

New video up!

does it smell with the high flow cat? cuz my catless stinkssss

[@kniffswelt]

A little bit. I had catless dps on my 335i and smell was horrible at redlights, high flow dp way less smelly

[@NoSmileification]

200 cell will still smell occasionally, 300 cells rarely but won't be as strong. 400 cell or above you shouldn't smell anything. 300 cell is the sweet spot and doesn't really offer much difference in performance loss compared to a 200 cell.

@@NoSmileification Inside my garage it was just a tiny bit of smell when i disabled coldstart. so it depends but yes, if you want to go safe go 300+

Yes it passes inspection in Sweden with these mods.
