This is my 05 daily driver.  I have the K&N intake, Banks High Ram, MBRP 4" to 6" stacks, as well as front and rear airbags with the on board tank and compressor.  Oh and an amp'd PA system you can hear from over a block away.  When I was up in Ohio I used it for tug-of-war and sled pulling.  There isn't a lot of that going on here in Amarillo so now I'm starting to set it up for speed.  This might take awhile.  They be some expensive mods.
