    Pure Aggression. This special Flowmaster American Thunder Stainless Steel cat-back exhaust is pure aggression for your truck. You'll intimidate those around you thanks to the deep notes this specially designed kit makes thanks to 3.5" popes and 4" end cap. The kit is made to put out the most sound possible and you'll be amazed at how refined and intimidating this kit is overall. Add it to your truck and you'll stand out everywhere that you go for sure.

    Faster and More Powerful. This Flowmaster American Thunder Stainless Steel cat-back exhaust kit will improve the actual torque of your truck when it's installed. It does this because the wide pipes and smooth path helps exhaust move more quickly. The exhaust will flow through your system in less time and leave you with an engine that continues to perform like you want it to for years. You'll get more power out of the engine because it can keep running at peak levels all the time.

    Supreme Strength. This kit is unique because it's made from some of the best materials that you can get your hands on for an exhaust system. The pipes, the muffler and the tip are all made from T-409 stainless steel that's mandrel bent around the corners. That means it has a consistent diameter and that it won't rust or corrode with time. You get a system that's very tough and that will hold over the years.

    Put it on Fast. In just a few hours you can put this Flowmaster American Thunder Stainless Steel cat-back exhaust into position It locks onto stock hangers and doesn't require much special work or tools to make it work. It's possible the unit will need some trimming depending on the length of your truck bed, but there's a good chance you can just attach the pieces and go.

    Application. This Flowmaster American Thunder Stainless Steel Single Side Exit Cat-Back Exhaust is designed to fit on all 2011 to 2014 F-150s powered by the 5.0L engine.

      Flowmaster cat back

      Exhaust sound great. Had a few issues. One they sent me the wrong clamps. Two the back hanger was bent so bad it would even go in the rubber isolated. Three the tip was scratch really bad straight out of the box. This is pathetic for a $700 kit
