2005-2023 Dodge Challenger, Charger, Magnum and Chrysler 300 Kooks 3" Connection Pipes 

If you are adding a set of KOOKS headers to your Dodge Challenger, Charger, Magnum or Chrysler 300 you will need to get one of these Connection Pipes to connect the headers to your exhaust systems. You have the choice of three different styles. The off-road selection has not cats and is not legal for street use. The next choice is race catted connection pipes which are 49 state legal. The last choice is the GREEN CATS. These cats are capable of supporting 900  hp and can clear most Check Engine Lights.

Kooks has been building headers since 1962. And in that time they have learned how to get the best power and performance from a high-performance engine. Kooks exhaust systems are designed and built here in the United States
