.48 or .63 A/R for stock LS?

RedDAinteg- I would like to call dibs on the intercooler, downpipe, and oil lines.

is the oil lines the hole stealthmode kit like on his site? the one that is $90?

is the downpipe brand new?

and what size inlets on the intercooler, and how long is it end to end?

thanks!

i have a tial 38mm wg that is atmosphereic and it is placed rigth on the collector of my ram horn manifold and i am getting boost creep and the only thing i can think of is that the .48 houseing is too small … anyone got any ideas?
