My truck is the same year as yours and with the stock exhaust I can hear a pretty good whistle while driving between 5 and 10 pounds of boost and I am trying to save up for my exhaust at the moment. It really has to do with the number of vanes on the turbo that causes that whistle and the 03-04 models have the best whistle in my opinion.
I know that my 03 with the stock exhaust whisles louder than some of the newer trucks with a modified exhaust. It is really nice when I have the rear wing windoes open and a hard surface beside the truck......

Nope. Quick mod, just dont go mudding of anything activity that will present some serious crap flying into your turbo. My boss at WWR ( worldworldwideturbo.com) told me to do it, and it sounds sexy sexy sexy. He shoudl know he has a fleet of twin turbo cars all open turbo. But we will be fabricating a custom intake next week at the shop.

Back when mine was running, She whistled dixie!. Just had the cat and muff cut out and piped..and a K&N cold air intake..I was up to 18 mpg at one point but she died off after a while.......Just about the time I think the head gasket started going south..... New heads, banks intercooler and banks intake..... I might get back up there to 18 mpg.... We'll seeeee

I put the Accufab performance elbow in my Excursion and the whistle increased substantially. I also gained power and 1 MPG which didn't hurt!
From Accufab website:
Features include:
Airflow increased by 40%
Lower EGT's
Increased mileage
Less back pressure
Boost port for aftermarket boost gauges
Available in a cast or cast polished finish
Independent dyno tests, conducted at JDM Engineering, showed a 9hp advantage over stock with no other changes and an equal increase in torque. The reduction in back pressure alone will increase the life of the turbo.
