This was my chaotic work space.
The light corrosion around the welds in the following pictures really makes things look worse than they really are. If I had the energy I could have prettied the piping up. The inside of the
piping, where it really counts, is smooth and condusive to good gas flow. 
1: BOV from an old Volvo
2: Collector piping
3: Downpipe and exhaust pipe
4: Homemade turbo flange
My first abstract work of art. The intake piping in the bottom left was made from 2.25" piping. The collector piping is 1.75", merging to 2" after the 'Y'. The downpipe is 2.5", with the
wastegate outlet 2". Just above the "2" in the picture you can see where the piping expands from
2.5" to 3". You cannot appreciate the size of 3" exhaust piping unless work with it. It's thicker than a boa constrictor.
Notice the cast iron 'Y' connecting the front and back cylinder banks. This broke when I used
excessive force to make the collectors fit on the car. I created a 'Y' from scratch using spare piping I had.
Another view of the collectors.
A good shot of the 3" exhaust system. The muffler I used was Summit Racing's own in-house high performance brand.
This part was a pain in the ass. The flange you see attaches to the exhaust side of the turbine on the turbocharger. The bottom pipe (2") is where the wastegate dumps exhaust gas, and the top
pipe (2.5") is the turbine outlet. The flange had to be custom made using two standard flanges which were cut, welded together, then ground flat.
