Stepped Tri-Y Header Design
Kooks engineered the headers with a stepped Tri-Y configuration using 1-7/8-inch and 2-inch tubing. Combined with the oval port design and stock bolt pattern, this application-specific configuration provides a performance-oriented exhaust path designed around the C8 Z06 and its 5.5L engine.
5-Inch Ultra GREEN Catted Connections
The kit includes Kooks 5-inch Ultra GREEN catted connection pipes matched to the stepped Tri-Y headers. Their flanged outlets connect directly to the OEM exhaust, allowing the upgraded header and catalytic converter assembly to integrate with the factory exhaust system without requiring separate connection pipes.
Included Heat Blankets
This 2181HY30B package also includes heat blankets specifically for the Ultra GREEN catalytic converters. By including the heat blankets with the headers and catted connections, Kooks provides the components together as a complete package for this C8 Z06 application.
304 Stainless Steel Construction
The headers are manufactured from 304 stainless steel for excellent strength, durability, and corrosion resistance. This premium material is well suited for the high temperatures and demanding operating conditions associated with the C8 Z06's high-performance 5.5L engine.
OEM Exhaust Integration
The included Ultra GREEN connection pipes feature flanged outlets designed to connect directly to the OEM exhaust. This allows the complete Kooks header and catted connection package to work with the factory exhaust layout while eliminating the need to source additional connection components.
