    817666 is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from awesome exhaust 2015 Silverado double cab 5.3 . first I bought the outlaw version which has a very small muffler and produces a ton of interior feedback sounded great but to loud for me. so I returned it with no problem I might add. add got the force II model. interior sounds is great and outside sound is what you expect

    Rated 4 out of 5 by from Love the sound, but the clamps could be better. I love the system it sounds good, but not to load while riding down the road. My little boy loves the sound of the truck also. I suggest if you do purchase this system look for alternate clips to hold it on.
