thanks Artemis!
To the OP - not to be a killjoy but check your diffuser/exhaust tips in a couple days. From pictures I've seen the SLEK diffuser has less clearance than the vorsteiner (what I have). On my vorsteiner with Akra slip on, I have ~ 8mm vertical clearance between the top of the exhaust tips and the diffuser, but there was still some marring of my carbon tips and diffuser. For now I have placed some 3M rubber pads on those areas to eliminate contact between the tips and diffuser. If that does not work I will probably swap out the rubber hanger mounts.
FYI the part number for the 135i rubber mounts is 18207578238 #6 in this diagram
