I have a set from Funk Motorsports out of the UK, and planning on installing ASAP in my S55 M2C.
Videos and other evidence seem to support this being a good idea, and willing to give it a shot, even though the install is a bit of a bear. I will have a full DIY up asap though with two turbos its a bit larger challenge.
Actually there is one bolt on the OEM heatshield that makes the whole job 3x harder.. **sigh** literally one bolt.
