displacement on demand, it cuts out four cylinders when putting along. My 08 had the dod but not the vvt. not to sure if any trucks come with both.

lol i know exactly what your talking about!! when i got my truck i had super 44's put out in front of the passenger rear tire aswell, most annoying sound ever! so annoying i actually ripped off my exhaust and redid it 4 or 5 times, and my conclusion is, for best sound that you cant really tell it switches from v8 to v4 mode, remove the resonator, and y pipe, have custom 2.5" piping true dual ran all the way to an x pipe then true dual out the back with no mufflers to two 4" tips coming out the back at 45 degree angles, very impressed with this setup, its very loud, my friends say my truck sounds like a drag truck, once i get longtubes, and cams i cant wait! did removing the DOD for anyone make them get real crappy gas mileage btw? im removing mine but very sad to see the 19adv mpg per tank go

Before i turned off the v4 mode with efilive the exhaust sound was so bad and the vibration was horrible. Having open y pipe it would rattle all the heat shield nuts loose causing an annoying metal-rattle. I was so happy when i turned that **** off
