IMPORTANT: Please Read Below!!!
If you want the KC fighter jet whistle then order a 2003, the 2003 will bolt on the 2004-2007 trucks but you will have to run 1 less bolt. The 2003 will spool slightly slower, make slightly more power, and have that famous Jet Whistle you are looking for.
If you want LESS WHISTLE then order the 2004-2007. This version will whistle less and build a little more boost at lower rpms, but will make a little less top end power. This version will not fit a 2003 turbo without extensive modification. Please contact us with questions.
