Nice to know they have a good rep in the Focus world.
They responded quickly to my request for installation instructions. Given the depth of the cooler is 7" (2.5" thicker than Whipple's) I figured the lower shutters would have to go, which they confirmed to me vie email. Their install instructions look pretty much like the other vendors, however they don't make mention at all of the shutter assembly, never mind how to remove it. I think the Garrett instructions cover the shutter removal quite well, but I wonder if there is anything else missing / undocumented?
I was just about settled on the Whipple, since it is proven, however I wouldn't have a problem forgoing the lower shutters for this beast - especially at the same price. I am just worried about installation headaches.
