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 what a HEMI should sound like. The Ram factory exhaust is horrible this was a game changer and affordable.

Very straightforward install and sounds amazing. Just wish it came with the hardware required to install onto the flange. They say to use original on the instructions but mine were so rusted that I had to use a cutoff saw to get them off.

5.0Cat back system
Took 45 minutes to install. Makes my 15 Silverado sound better
5.0Great sound, not as loud as I thought it would be
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.
