I am currently building a 6 into one tubular header to hold a garett t3 turbo for my 2.8L 1987 BMW 325ES. After I finish testing and expose any flaws that need corrected. I'll be able to reproduce this header with the jig I built. I may build a set or two if there is any demad for them. Also in the works is a liquid to air intercooler designed to fit with out cutting.
