LS1 single turbo build?

long story short
i started ordering parts today.. i ordered a Turbonetics, GT-K650 (yeah the new ones), HP Newgen wastegate, Godzilla blow-off valve, and another Mast M90 ECM.. i don't plan on starting the build until the weather turns crappy for
answers-
i would go ahead and pipe the exhaust around the back of the engine.. use some good high quality wraps for all of the exhaust components to lower temperature in the engine bay..
i'm not sure as to why you chose I beam rods
