I have a late 2007 335i E90 and just fitted a new Helix FMIC and ER charge pipe.
I got the 09+ ER charge pipe (long version) AND got the 09+ Helix FMIC WITH the hard J-Pipe.
You'll see the extra J-Pipe below (available upon request from Helix).
Everything fit perfect and the entire 'cool' side of the FMIC piping is replaced going by this method.
The throttle response is amazing! And am guessing it's due to the whole cool side piping now being solid rather than plastic / rubber.
Hope this helps someone.
It is, mine is all hard piped to...I have a ER short pipe and ER hard pipe......that is where my issue is.
