The K27 charge pipe adaptor with orings works fine as long as the exhaust headers mount the turbo in the right position.
A 4ply silicone hose works just as well if you cut off the bottom of the charge pipe leaving a small lip to help seal inside the hose with clamps.
The hose makes it alot easier and quicker to line up a turbo that doesn't line up with the oring setup.
Also, orings will eventually leak to some degree and there's no way to check that while in the car... race cars use silicone hoses and doubled up hose calmps or t-bolt clamps or even wiggins clamps because they don't leak and allow some movement.

Call and make sure which ones are which when ordering. I've forgotten the part numbers and go by diameter and location when ordering. There is one for the throttle body and the oem turbo bypass valve if usng that too.
