For those that want to custom build thier own low mount TT system, I have stainless or aluminized up-pipes for sale with 38mm wastegate flanges on each. 500 for aluminized pair, 650 for stainless pair. These are to be used with the stock manifold. Here are pics of the up-pipes seperate and with turbos mount on car:
