      Stainless Steel Construction. Dynomax uses rugged 409 stainless steel throughout the construction of this exhaust kit. The material easily handles debris without denting or breaking. It’s polished to a sheen and has built-in protection against rust and corrosion.

      Direct Installation. This kit comes with all of the hardware you need to conduct a direct installation with no vehicle modifications. Note that a jack and stand are recommended so you can raise your vehicle safely to replace the exhaust.

      Limited Lifetime Warranty. Dynomax backs this kit with a lifetime warranty against material defects and problems with manufacturing. This is a non-transferable warranty that is voided in most cases of user damage, such as accidents or neglect.

      Application. The Dynomax Ultra Flo Welded Cat-Back Exhaust is made for use with the 2007-2011 versions of the Jeep Wrangler JK 4-Door that have 3.8L engines.
