I know this lil place you can buy one

DRP LB7 Intake Horn for 2001-2004 LB7 GM Duramax

You will get a little faster spool up, a lil more boost, lil more turbo whistle and a slight drop in egts with one.

Its a cheap must have mod for any stock turbo LB7, made a big difference in my truck as far as spool goes, and it makes cool whistle noises.

It has 3 10mm bolts that hold it to the turbo, mine is Federal emissions so it was easy, but the Cali trucks are a bit more of a PITA. Yes the whistle is alot more noticeable in the cab.

Its not horribly high pitched like a cheetah or anything, just makes the current noise a bit louder
