R53 Racing Dynamics Header

Has anyone installed this header onto their R53? If so, what are the reviews?

It says a high flow cat but the pipes from the cylinders do not appear to be longer that normally works out to less restriction.

RD stuff is just a name. I would recommend an actual long primary header.

While the primary tubes look similarly short to the original, the collector arrangement looks to be a little better designed.
I would not buy this one for improvement, but I'd buy this over an OEM assembly if the original was leaking, or bad in any way.
