I think so too, can you provide a link to the GT2 ducts, if available?
I'd like to understand the design differences between the GT2 ducts and whichever variety gunner went for. On first glance the former appear to have a curved and narrower opening... anything else? i.e. cooling hose to the brakes?
As an aside, in the absence of TechArt ducts, these ducts still appeal.
