Upgrade the exhaust flow of your C8 Corvette while retaining premium catalytic converter technology with the Kooks OEM x 3-inch Ultra-GREEN Catted Connection Kit. Designed for high-performance street and track applications, this system replaces the factory catalytic converters with high-flow Ultra-GREEN units for improved performance, sound, and durability.

Built from high-quality stainless steel, these Super Street 5-inch bodied Ultra-GREEN catted connections feature flanged inlets and outlets with stock bolt patterns for a precise, OEM-style fit. The inlets connect directly to factory manifolds or Kooks headers, while the outlets bolt straight to the OEM cat-back exhaust. This kit includes the required gaskets, bolt kit, and Kooks heat blankets to help manage underbody temperatures. Fuel-compatible with pump gas, E85, and unleaded race fuels, this setup is ideal for modern high-output C8 platforms.
