Kooks Super Street Ultra GREEN Catted Connections for the C8 Corvette Stingray

The Kooks Super Street Ultra GREEN catted connections are the missing link between your OEM manifolds or Kooks headers and the factory cat back on the C8 Stingray. They add flow and tone while keeping an emissions minded high flow catalyst in the system.

These 3 inch stainless pipes use Kooks Ultra GREEN EPA style metallic cats with a high cell count substrate and a 4.5 inch outer diameter body. They are built to connect directly to either the OEM manifolds or Kooks long tube headers on the inlet side and the factory cat back on the outlet side, so you get a true bolt on upgrade without having to replace the entire exhaust.
