my 04 cummins, had a levelling kit, Nitto Terra Grapplers, Air Dog 150 GPM fuel system, Straight Piped with a 6" tip. I miss the motor in this truck, that's it! couldn't stand the ride/comfort/interior.....ONLY liked the motor...i fell for the looks and the motor. if ford had a cummins, and sleeker looks, they would have the ULTIMATE truck lol
