well i would say a lot of it will be the tires, i have drove with them and they are loud.
It looks like you do have a long arm kit on it so that is good, with all that lift.
i just had a 88 with a 9.5" lift and a long arm kit and it was loud as hell. i would say get used to it if you want it that big.
what kind of noise is it that you are hearing?
