Bring a Kooks Tri-Y upgrade to your flat-plane Z06
Give your 5.5-litre C8 Z06 a stepped Tri-Y header upgrade while retaining the option of its factory catalytic converters. These 304 stainless headers step from 1-7/8" to 2" and use flanged outlets that connect directly to OEM cats or matching Kooks connection pipes.
SKU: 2181Y500
Stepped tubing and a Tri-Y layout
The primary tubing changes diameter along its length, while the Tri-Y layout brings cylinders together in stages. It is a specific header design for the Z06, rather than a generic long tube conversion that requires you to replace the front cats at the same time.
A choice of front connections
The oval-port headers use the stock bolt pattern and include the gaskets and bolt kit. You can fit them to the factory catalytic converters, or choose matching Kooks connections when upgrading the cats as well.
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.
