I was told that the American Racing headers for a 2009 E63 amg would fit my w212 e63. Can anyone input on this fitment!!

 

2009 is a 6.2V* NA, 2012 are 5.5V8 TT, don't think they are compatible.

 

^^^^ EXCEPT the OP has a 2010 with a 6.2L so yes it would fit. My understanding is that the AR and MHP (modern horsepower) are the same headers. MBH makes really nice headers and would be my choice for the M156 engine.
