Upgrade your Z06 headers and catalytic connections together
Make the most of your Z06 with a matched set of Kooks stepped Tri-Y headers and Ultra-GREEN catalytic connections. The 304 stainless steel construction and LT6-specific design make this a substantial front exhaust upgrade, while the factory-style rear connection lets you keep your existing rear exhaust.
SKU: 2181HY30
Stepped tubing, purpose-built connections
The primary tubes increase from 1-7/8" to 2" and merge through a Tri-Y arrangement. The kit pairs that header design with Ultra-GREEN catted connection pipes, so the two parts of the front conversion are already matched. The oval ports and stock cylinder-head bolt pattern suit the Z06 LT6.
Keep the rear exhaust you like
The flanged connection-pipe outlets join the OEM rear exhaust. That is useful if you enjoy the original rear system or already have an aftermarket system with the same factory interface. Have the complete installation checked for sensor routing and heat clearance before the car returns to use.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.

Frequently asked questions
Are the catalytic connections included?
Yes. This kit combines the Tri-Y headers and their Ultra-GREEN catted connection pipes.
Which Z06 engine is it for?
The C8 Z06 5.5L LT6. Choose a Stingray-specific system for the 6.2L LT2; the shared C8 name does not make the headers interchangeable.
