Do all F30 328i’s have an exhaust flap?

[@projectf3075]

Yessir. All F30s do, including the 335i/340i as well

[@RimvydasSad]

@@projectf3075 how about the e90 LCI? i got 328 and its loud in the morning for 15 seconds, but after closes. Any ideas to leave it opened all the time? :D

​@@RimvydasSad leave it in sport+ xD

Cooooool

[@MohVlogz]

No change

You can also put it on sport mode to open up the valves instead of modding it

[@turinwarrior]

UssGo really? The only available option in bootmod3 is to open the valves in sport mode. that feature would be useless then.

turinwarrior sounds exactly as mine in sportmode, try it on eco mode, sounds even better
