Okay, so I wanna create a turbo setup. I pick up a turbo, intercooler, wastegate, BOV, manifold, and other things needed. Is there any website or something where I can buy prefrabricated piping(Charge Pipe and Down Pipe)?

 

For charge piping you can go to www.speedpartsrus.com "customcoach" They had a group buy not too long ago for charge piping. One of your local muffler shops should be able to make you a downpipe.
