I have an appointment this Wednesday to install some j-pipe (1/4 wave resonator) and from my research I will go with 36" long for my 535i and maybe ask for it to be ajustable in length to be able to tune it. Hopefully I will no longer have drone at highway speed

UPDATE:
I installed J-PIPE of around 36"-37" long and it reduced the 1800 RPM drone frequency by 15 db! (recorded before and after with RTA analyzer for IPhone) It also reduced considerably the drone of any RPM between 1200 to 2200 which make the slow acceleration in comfort mode a lot quieter and without making everything shake in that car anymore. I am very happy with the result! Drone is very minimal now and I can listen to low volume music again!

i'm trying to understand this mod. i know Bmw double you have something similar? so basically you tapped off your pipe close to the middle with smaller piping and than closed the end? with Bmw doubles he has a removeable cap which makes sense but here it looks capped off? i only asked because once i slap those Meisterschaft's on i know it's going to be loud even tho it has EVC

For example all frequencies from 40hz to 600hz where from 55 to 80 dB at 1800RPM except 100hz was 95db. So I calculated the length of the pipe to cancel 100hz sound and now the 100hz frequency has the around the same dB has the others. Clearer now?

Today Ive tried to place an M5 Diffuser on my 2013 535xi M sport, and when me and my friend tried putting on the diffuser it would not go in because this "bar was in the way" ? What is the fix for this. I have the comfort access and will not care if this feature were to go away. Do i need m5 parts? Where can I go to get this installed if this is the case? Somebody help me out..
