Have you checked out ls1tech? Guys usually run 3", 3 1/2" and rarely 4" dp on the ls projects. Some people tried to run 5" downpipes but lost TQ down in the bottom range of the curve. Also, running a 5" dp will hurt the spool time of the turbo. I have been doing tons of research because I would like to run a single turbo in my camaro.

Yea I know. Its more of a for looks thing. I'm not worried about power loss, she is giong to have enough torque to compensate.
