Twin Piping

I'm doing mine all out of Polished stainless steel. I am finishing ordering the parts as I type.

You can get parts from source Automotive, airFlo, just about any big rig shop too.
 
When I looked into getting twins, I checked out BD, MPI, II, and source automotive.

Source's kit was by far the best of the 4. The kit went together just like it should, without any grinding or fitting. The bottom mount for the turbo is built like a tank, and the primary to secondary piping is all one size -- not stepped down and then stepped back up like some of the other kits.

Do your homework before you make a big purchase like that.
 
We used 4" prebent steel pipe from a Big truck shop. Work very well and saved money.
 
Fits perfectly in line with the intake of the primary and secondary. Don't need to frabricate any necked down and up pieces.
 
Read a little closer,3.9 isuzu. Probably a good turbo for it on the top. I build my own, the first set took a while. They are easy once you do it for a while.
 
a few guys on this site turned me toward a truck supply that sold "imperfection steel" for a very discounted price...$10/elbow. i walked out with enough 4" & 5" exhaust elbows to make the cold pipe and intake tube for around $70 (bought a couple extra for misc. parts)
 
I really like the 3.5" Slip fit elbows from www.airflo.com if you get 3 tight radius id/od elbows and about 6" piece of straight pipe and a 3.5"-3" reducer it all fits together perfect once you trim the ends a little.
