Thanks man i appreciate it. I am gonna really try to see if if they will let me swap for the 1.5 pipe. I really dont want to cause excess lag, i imagine i could probably get away with it if i had big port work but im still stock ports so i bet it would be really laggy. I could always tig around the holes of the engine flange and machine it back off and bore the holes again. A lot of work but might save me some money trying to make another. Do you recommend making a little longer manifold like the ones that you create then just a short stubby one? Also are the tial 38mm v band flanges to the manifold also fit the 1.5?

 

Looks like im just gonna go ahead and use the 2in pipe for the manifold runners and buy some 1.5in pipe for the wastegate runners. It seems that quite a few people do the 2in piping like full races manifolds. Himni Racing wont get back to me to make a trade out for the 1.5in piping.. go figure. Hopefully its not too laggy on the stock ports.

 

So i took off my manifold to throw in the id2000 injectors on my stock fuel rails for my s5 tII. They are cut and welded with fittings for the pressure regulator. Are these not drop in replacement? Is there any adapter i need to be running?
