I started the Super "B" turbo install this weekend. The Down Pipe was the biggest challenge as the turbine housing protrudes back a bit further than normal.
Finished fabricating the down pipe. It's 3 1/2 at the turbo and tapers to 4".
I had to Oval the 4" pipe where it passes through the cab and frame. Talk about tight!
Here is the finished DP after a coat of heat paint. (I'm sure it will bake off)
After cutting the heater hoses and moving them more torwards the firewall there is just enough clearance.
I installed a stainless flex joint at the DP with a V-Band clamp.
Re-routed the exhaust to just under the rear of the cab, and added a ATS stainless muffler.
I still have to fabricate the exhaust hangers and make the tail pipe. I converted the truck to air ride suspension and moved the batteries to the frame under the cab. So, I will probably add another V-Band between the muffler and tail pipe.
Next I will start the install of the Duramax IC and IC plumbing I picked up a Pennisular Intake so the install should be easier.
