      Description

      Bring the Thunder. Your 2009-2018 5.7L Dodge RAM 1500 w/ Factory Dual Exhaust needs to have a beefy sound to match its power. So you need to bring the noise with the Flowmaster American Thunder Aggressive Sound Cat-Back Exhaust - Split Rear Exit, with its full-stainless design and powerful sound. You'll feel the gains instantly. 

      Superior Design. The 3-inch stainless steel tubing provides powerful exhaust thanks to the mandrel-bent design that provides a superior boost in flow against stock bending. You'll see a powerful boost in horsepower and torque while the super-tough stainless steel protects from weather and debris. 

      The Sound and the Fury. The included Series 50 muffler provides superior flow to belt out an aggressive, heavy sound that's sure to rattle the windows of some lesser vehicles on the road. The split rear exit is topped off with 4" stainless steel tips polished to a brilliant shine. 

      Installation. This is a completely bolt-on install requiring no modification to your Dodge RAM. Just use some hand tools, a car lift or jack stands, and a friend to hold up the pipes as you put them in. 

      Lifetime Limited Warranty. This is protected from manufacturer's and material defects by a limited lifetime warranty. Please see full warranty for complete details. 

      Application. This Flowmaster American Thunder Aggressive Sound Cat-Back Exhaust - Split Rear Exit is designed to fit 2009-2018 5.7L Dodge RAM 1500 models equipped with Factory Dual Exhaust.  

      TECHNICAL NOTE: Does not fit trucks with factory single exit tailpipe

        Great product fast delivery sounds amazing. Had it welded on instead of clamps so can't comment on the clamps if good or bad. Starting up the truck sounds like a lion roaring. Must buy

        Even a Girl could do it...

        Easy install, perfect noise level and right amount of an awesome throaty rumble. It took a few hours to install only becuz I had to grind the muffler clamp off the original 40 series muffler. Other than that, everything went in like butter! Great directions to follow, heavy duty parts and it was seriously an easy install. I had a great time doing it and I'm a 4'11" chic ! I was going back and forth between the American Thunder and the Outlaw, and I'm very happy with my decision, great choice.

        American Thunder direct fit exhaust system

        This is the first upgrade I've done to my truck. I couldn't be happier with the results. The exterior sound is awesome, at an idle and ripping down the street. Interior sound is also good. Not obnoxiously loud cursing down the street. Super easy to install as well. Had this unpacked and installed in about an hour to an hour and a half. overall, awesome system and easy to install. would certainly recommend this to anyone looking for an upgrade.

      Does this fit 2011 Ram 1500 5.7 V8 Quad Cab Big Horn

      • As long as your truck came with a factory dual exhaust system this will fit.

      FLOWMASTER® 40 SERIES ORIGINAL MUFFLERS I had this series on my 2006 Dodge Ram and Loved them. Can I get these on my 2013 Ram 5.7 V8 4x4 with factory twins on it already. Also looking for the pipes and hangers for it as well and the double wall tips.

      • At this time, Flowmaster does not make a kit that uses a 40 series muffler for your truck.

      is the American thunder direct fit muffler available without pipes like the outlaw?

      • At this time we do not carry the Flowmaster American Thunder Aggressive Sound Dual Exhaust System as just the muffler like the Flowmaster Outlaw Muffler is.
