2mm, Wafer thin?? So, how thick are manifolds that you have experienced then? I no longer have the Polish manifold, but only because I sourced something I liked more.

2mm in enough in my opinion, but I went on the cautious side this time with 3mm. I guess we will see within the next few weeks how this will work out. The wastegate is in a slightly different place now and I have just finished building the screamer pipe, although there are further changes planned for that once it is all up and running.



The thing I like most about it is I have done it ALL myself. I don't owe any thanks to anyone, well except Gary for letting me use his resources.
