Keep the Z06-style rear exhaust with your revised headers
This revised Kooks X-pipe gives your naturally aspirated Z06 a matching catted connection for the newer TORCA-clamp headers. Its three-piece crossover and 3" rear mid-pipes join the OEM Z06-style exhaust, with fitting clamps included.
SKU: 21613201
Choose the revised header joint
The front connections use TORCA Swivel-Seal joints. They fit the revised Kooks C6 headers; the old two-bolt flange headers need a different X-pipe.
The complete crossover connection
The stainless assembly includes 3" to 3" mid-pipes and all necessary fitting clamps. Its Performance cats are for naturally aspirated use, so this is not the catalyst choice for a supercharged ZR1.
Matching products
For your naturally aspirated 2006-2013 LS7 Z06, the revised Z06 / ZR1 headers have the matching TORCA Swivel-Seal front joint. These Performance cats are not for the supercharged ZR1.
