I've got a Xantia turbo to FMIC pipe that I'm using to get from the inlet manifold as it fits nicely and has a boost feed for the LDA.

I've also got the turbo xantia pipe which I intend to use as it avoids the costly option of using multiple silicone bends.

Are these restrictive enough to warrant using metal piping?

Cheers.

How do you mean restrictive enough?

They have quite small inner diameter at certain points where it bends.
