Kasey, any pics of yours online? It's a little late for me know but 2 weeks ago when I was fabbing my twins into my 03 F-250, I would've love to see how someone else did it. I ended up using an ATS 3 piece exhaust manifold with no spacer between it and the secondary turbo and then used one of BD Diesel exhaust elbows to connect to the primary. I kept having clearance issues with the A/C/heater box so I had a 2 inch spacer machined and added it to the bottom of the BD elbow. It spaced the primary down low enough to give me heater box clearance and gave me room to run the tubing out of the top of the primary and up to the secondary.
