Hey guys,
After the replies I got to this on MBworld.org

I think I've come to the conclusion that the Stock SL55 Inlet hoses (which are now sold WITH the SL55 Y-Pipe) also require some minor modification to make them fit...But not as much as these stock ones.
SO, you would likely be better off buying the SL55 Y-Pipe WITH intake hoses...and modifying the SL55 Intake hoses to fit. This will cost you around $120 IIRC.
The part # I posted above is the Y-Pipe ONLY..
The part # with inlet tubes AND Y-Pipe should be : 1130900129
Purchase the Y-Pipe WITH the inlet tubes if you want to make it a little easier (but more $$).
