If you live in one of those locales where you have to pass an annual emissions check, it ain't gonna cut the mustard.

It won't hurt the performance at all, alot of people are running straight exhaust on their 6.0's. It's just louder.

Actually you can still pass emissions just depends on how they do the testing. Here it is just the OBD-II testing(which is a joke), now back home he would be up that well known creek because they do everything from the computer to visual. I run a 5" straight exhaust and it is definately louder(but I have an aftermarket turbo too which whistles louder even more then the 03 turbos and I did have an 03 turbo on mine when my factory one crapped out on me).

The one thing I miss about not having the 03 turbo is that it would whistle at low speeds and be gone on the highway while it's the opposite with my new turbo. Loved going thru parking lots just doing 15(never enjoyed doing 15 til I got that turbo) and confusing people that didn't know what it was making all that racket except for the fact it was coming from my truck.
