s300 and s400 differences

get it installed yet?

just got it in today. They were closed last thursday and friday. They did forget my Vband clamp and S400 based exhaust flange. Hurry up and wait right. I'm tired of my truck being down. Hope to get it running by saturday, but it really doesn't matter. I'll be shipping my injectors off next week and upgrading to a set of 5x16's

So when I order mine what do I want to remind them to ship along with the turbo? I have a 3 piece ats manifold

It's my downpipe exhaust flange they forgot. They sell it as a kit. supposed to include the vband and a weld on vband flange that I can weld to my downpipe.
