this is a pain in my backside too.
I want to improve that whole section from the turbo to the IC inlet.
SFS are almost there with the outlet, and the IC inlet is already in production, just need to sort the pancake now, ideally avoiding the poorly clip system.
If the connection at the turbo uses an alloy connector, and it also clamped, then at the other end of this pipe, its clamped (jubileed) onto a modified pancake, with the same on the out side, then with the alloy fitting and clamp onto IC in, that should be strong enough.
Thats what Im hoping to achieve, if you understand lol
edit - what materials are the PD150 / 1.8T pancakes? my PD150 looks like some sort of alloy, but from what photos Ive seen of the 1.8T version, it looks like it could be stainless?
