Welp, I called up Huron Speed today. Cost me some money, but I think it's going to make the hot side install easier and yield a better result. I got their downpipe which is made to work the manifolds I got secondhand on market face.
I also decided to the ditch the eBay GT45 turbo for a VS Racing 7875.
