Those are the ebay twin headers and the chinese P-trim t-3/t-4's I really have heard good things about those. That guy is full of it though: If you run a stock motor at 27psi you will pop the gaskets and destroy that motor in a hurry. Not to worry though, those turbos are only capable of 14 psi or so on a small block (383 ci or less). Thats a pretty good deal if the turbos are in good shape.
As for the plumbing: it isnt too hard. The trick we use is to get the polished aluminum tubing and then go to an exhaust shop that uses a mandrel bender. The tubing (3" X 8') typically cost around 120.oo and the exhaust shop will bend it for around 200.oo. Simple, cheap and easy. G-bodies have a lot more room for underhood plumbing.....
