Our Outlaw® Series Exhaust Systems/Kits feature race-bred components that ensure minimal restriction and only slight reduction on sound over open exhaust tubing on non-catalytic converter-equipped vehicles.
Sounds good a bit loud but good. I would probably choose a little quieter in the future
Love this sound. Deep sounding rumble when you turn it on.
I love the sound. Very aggressive note. It tucks up really well.
easy to install, looks goood and really sounds nice
Sounds what a HEMI should sound like. The Ram factory exhaust is horrible this was a game changer and affordable.
The outlaw exhaust is not very loud in the cab of the newer trucks if you like the sound of the engine.. the Silverado AFM system sucks and will be deleted soon. Great product.
Great sound and easy install. Harder to remove old than it was to install new.
Super easy install and I absolutely love the look. I wish it was a little louder, but I like really loud exhaust myself. I knew it wasn't going to be as loud as I wanted but I liked the cost and style so I went with it anyway. Definitely met my expectations.
