Hello all,

I had a question. I currently have a 435i with Challenge Sport exhaust and feel like it's not agressive/loud enough for me. It is OK when it sports mode and car is all warmed up, but normally, it sounds "stockish."

Does anybody know whether the Active Autowerke's exhaust is louder at cruising speeds or acceleration? Or how does it overall compare in sound to the Challenge exhaust?

Thank you so much!

Just go GT Haus, according to everyone on here it's the loudest, furthest-from-stock-you-can-get loud.

but i'm asking specifically for AA exhaust because it's a good deal,

so just wondering

The GTHaus is the loudest you can go with minimal drone.
Perfect option for guys looking for a loud exhaust

As you know Active is different than GTHaus. AA is for guys looking for a louder than stock exhaust but not too loud. I have seen vids of the Challenge exhaust and it sounds quieter than Active, but i cant tell you for sure since i have not heard the Challenge in person.
