Can anyone tell me about a place that makes custom downpipe for turbos. I have a 93 Hatchback with a d16z6 with with a cast iron turbo manifold that is located right in the middle facing down and im gonna be using a moroso oil pan, this is so you guys have an idea of where my turbo is. Is a t3/t4 turbo with the exhaust flange of 4 bolt, the one that is like a circle. I already have the flange but I was wondering if there is a place that sells them already.
