1-5/8" x 1-3/4" 304 Stainless Steel Torque Series Headers. 2009-2018 Dodge/RAM 1500 Truck 5.7L HEMI.

  • Heavy Duty 16GA 304 Stainless Steel Tubing for Improved Durability
  • Includes Provisions for EGR

A Catalytic converter takes the hydrocarbons (unburned fuel) produced by the engine and converts those toxic gases into water and carbon dioxide.

  • Helps remove harmful emissions from exhaust

  • EPA Certified Catalytic Converter

  • Elimination of check engine light not guaranteed

  • Rated for up to 425 Horsepower per Cat

  • Ok for use with Forced Induction


These two cats are physically the same, and both use the same 300 cell high-flow substrate. The difference is in the coating that is applied to the substrate. The coating on the Kooks GREEN Cat has more of the precious metals required to create the proper reaction to function as a catalytic converter in newer vehicle exhaust systems. This coating also helps the cat withstand the increased heat in higher horsepower and forced induction applications. The standard cats carry a 1-year limited replacement warranty (No warranty if used in a forced induction application). The Kooks GREEN Cats carry a 2-year limited replacement warranty.
