Turbo Log manifold

Hi, I`m making a new turbo log manifold as my current manifold, goes to close to the passenger on the passenger side.
I`m using laser cut steel to make it, but I wonder what thickness mild steel is best.
I recon either 3 or 5mm, probbaly 5, but what wall thickness have people here used? (and if it worked).
Thanks
Darren

The flanges are going to be 10mm, i was making the "log" out of laser cut steel to form a 3d shape fron the 2d parts.

I made the log part of mine out of a chunk of 50mm box section - that had 3mm walls and has worked fine. I can't pretend that it is exactly optimised for flow(!) but it fitted in the limited space available to me.

Nice setup, like the external wastegate. It is not much different from some oem manifolds. If yours work using more of a pressure, rather than directing the pulses, then I know the relatively crude pulsedesign of my manifold wil work.
What boost pressure do you run?
Thanks
