ok ready to do twins. But where can i pickup the pieces that i need to finish them. I have already got the turbos (62/71/14 on top s4oo on bottom) and 2nd gen manifold. all i want is the pieces i do not need a kit to just bolt up, unless it is a reasonable price. I know alot of you have built your own and i would like to do so my self so please share your info on what to do and what not to do, pipe size and thickness and etc... thanks
