In the end I’d say catless downpipes will all sound the same, surprisingly tho, switching I did notice a difference in the “pitch” of the pops/burbles and increased drone with a different catless downpipe that seemed to taper much quicker in size vs the ER downpipe which tapers nice and slow. Taper as in from the 4” turbo to the catback which is 3”? Not sure what the catback is.
However, ER downpipe has terrible fitment (that’s what I currently have).

How does the ER have terrible fitment? I have an ER DP from my 435i ready to install once I finish breaking the car in.
My friend has an ER DP installed on his M2 and nothing wrong with it.
I'm weirded out because another friend with an M2 faced some issues installing his Wagner DP on his M2 after removing it from his M235i.
So can you please clarify that a bit?
