The exhaust is awesome! Truck sounds really good. I have a cold air intake as well. Definitely notciable both inside and outside the vehicle. Highly recommended.

I like the sound alot, it does wonders for my GMC. Happy to havr. Also a gas saver. I did have one of the black tip scratched when it was shipped. Called and sent a picture. It was well rapped and boxed but scratched when put in the box. Called, sent picture of it and was told another was shipped to me. Not here yet must be coming by dog sled!

Installed Flowmaster's Outlaw system on my new 2016 Chevy Silverado along with a K&N Intake. I immediately noticed horsepower gains and better fuel mileage. The only negative issue was noted during installation. The pipes did not properly secure onto each other with the provided clamps. You are required to spot weld or modify the pipes by cutting an opposing slot to the one factory cut, which will allow the pipes to secure onto each other with provided clamps. Flowmaster is aware of issue.

Installed on my 2016 1500 Silverado Z71. Took me 2 hours to get stock one off and flow master on. Only problem I had was with clamps. Tighten them all the way and exhaust system still moves. Used other clamps and is perfect now. Love the sound!

The exhaust was a good fit and sounds great. Only problem is having to spend an extra $20 on better clamps cause the ones that are supplied DO NOT work.

I had a mechanic install it for me, but it only cost like 120 dollars to install it. The sound is really amazing, it really adds to the whole vehicle! I put it on a 2016 Chevy Silverado.

This exhaust is very aggressive. At idle it is very quiet with my 5.3 V8. With my foot on the pedal is very raspy and throaty. I'm always stepping on it cause it sounds great.
