      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.
