I'm in the market for a set of long tube headers for a 2012 C63 Black Series. Has anyone installed a set? If so, which did you go with? Which tuner did you end up going with?

The reason I'm asking is because I'm being told that long tubes don't fit on a C63 Black Series by Kleeman and a few other tuners have told me that they can't guarantee fitment because they've never actually installed them.

Any help would be much appreciated, thanks.
