Product Details
C8 Corvette owners looking to free up exhaust flow without losing catalytic converters have a compelling option in these Kooks Ultra-GREEN catted connection pipes (part #21803300). They replace the factory catalytic converters with Kooks's high-capacity units, bolt directly to the OEM manifolds or Kooks headers on one end and the factory cat-back on the other, and require zero tuning.
How They Work
These connection pipes sit between the exhaust manifolds (or aftermarket headers) and the factory cat-back system. They replace the restrictive OEM catalytic converters with Kooks Ultra-GREEN EPA-certified cats that feature a 400-cell, 4-1/2in diameter metallic substrate inside a 304 stainless steel body. The result is significantly better exhaust flow while keeping cats in the system -- and no check engine lights.
True Bolt-On Installation
Flanged inlet and outlet using the stock bolt pattern
Inlet connects to OEM exhaust manifolds or Kooks Super Street headers
Outlet connects to factory cat-back exhaust
Gasket and bolt kit included -- no additional parts required
No Tune Required
The Ultra-GREEN catalytic converters are specifically designed to work with the factory engine management. Install them, bolt everything up, and drive. No laptop tuning sessions, no worrying about warranty implications from aftermarket calibrations.
C8 Coverage
These connection pipes fit the 2020-2025 Chevrolet Corvette C8, covering the Stingray, E-Ray, and Z06 models. Built from T304 stainless steel and backed by a limited lifetime warranty, they are made in the USA by Kooks -- a company with over 60 years of exhaust racing pedigree.
Not CARB approved. Proposition 65 warning applies.
