Kooks Connecting Pipe Corvette C8 2020+

The Kooks 21803400 3-inch Ultra GREEN high-flow catted connection pipes are the perfect emissions-legal match for Kooks C8 Stingray headers, providing a direct bolt-on link from header collectors to the factory mid-pipe while delivering unrestricted flow and dyno-proven gains of 20–30 rear-wheel horsepower and 25–35 lb-ft of torque when paired with headers. Featuring 400-cell metallic substrate Ultra GREEN catalytic converters, these pipes light off quickly for emissions compliance and support over 850 HP from tunes or forced induction upgrades.

Handcrafted from T304 aircraft-quality stainless steel with mandrel-bent 3-inch tubing, 3/8-inch laser-cut flanges, and full TIG welds 100% welded construction, this kit ensures zero leaks under high boost or heat while maintaining factory ground clearance and heat shielding. The design preserves the C8’s exotic V8 soundtrack with a deeper, more aggressive tone and zero drone during normal driving.

For C8 Stingray owners who demand maximum performance with 49-state legality, the 21803400 Ultra GREEN catted connection pipes are the championship-proven link that completes the ultimate mid-engine exhaust system.
