Get the DynoMax Super Turbos Tim. (I guess Mopar made them quit using the Hemi moniker). Part # 17748. They will easily support the power level of your motor, they sound great at idle, the have a sweet wide open sound but they are not loud. They are $58 with free shipping on Amazon. Amazing # of positive reviews, 4.3 out of 5 on 69 reviews in the era where everyone is unhappy.

They have a “Hear it” button on their page. I haven’t since I know what they sound like, and with noise cancelling mics on smart phones you can’t really tell how loud somebody else’s truck is.

May not be anybody under 30 in this thread running them, but as you can see from quite a few of the posts above a lot of us who’ve worn out a dozen sets of tires on our trucks are fans.
