Without turbo vanes, its hard pressed to make it whistle. boost valve will help for $25.

cold air intake and staight pipe will make it put out some noise. or you could give fleece a call, there LB7 turbo is the loudest i know to exist.

you really wont get a lot of whistle out of the stock LB7 turbo like brian said its not a VVT. Some mods help but u still wont get a bunch out of it....best way is to get a diff turbo if youre that worried bout it
