Love the Super 10

Bought the Super 10 for my 17 Chevy silverado. Love the sound. If you are looking for a system that sounds mean this is the one you want. Cold starts are loud, loud of the line. But at a constant 40 or 50 can barely hear anything.

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!

Flowmaster Outlaw system

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.

Great rumble

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.

Good exhaust, perfect for what I needed.

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.
