Okay I will be starting a full build thread shortly.. I bought the twin Precision 6265's off Boosted One's 65 Duece.. Im going to be using the new Obx Turbo headers which have 3in outlets. I need suggestions on the hotside size pipe which will be very short and what size exhaust to use. For right now the setup will be on a 5.3 but within a year I will either have a 370 or 408 in it so I wanna build towards that route. I will be running twin tial 50mm bovs and Jgs 44mm wg's.. Any suggestions would be great. Hotside will most likely 90degree right out of the headers into the turbos.

Step it down to 2.25" then to the Flange. That will support PLENTY of power and still spool somewhat nice.

Thats what I was thinking as well.. I think I will able to squeeze either 3 or 3 1/2in dowpipes out.
