On the SVT cams there is a little overlap where the intake AND exhaust valves are open, what will happen is the boost will come in and go right out. If you have a free flowing exhaust it will go out easier and faster losing boost, if she's all bottled up then it will slow and you build more boost..simple explanation for a complicated process but you get the idea. Cat backs are always a good idea though.
You have the 3.33" 6-rib pulley and Vortech offers 3.125" (what I'm running my 3L) a 2.87" and a smaller one yet. You won't get any more boost unless you surpass the flow capabilies of that bosch bypass, then you'll get boost creep and it will creep up from 10psi. Run the 3.125" that will bring boost sooner and you won't out flow the bypass.
