Choose the rear connection for your Camaro build
These Kooks front pipes give you a choice between the OEM-size rear interface and a full 3" exhaust. Select Competition Only or GREEN connections, then match the outlet to the rear system you intend to run on your Camaro.
SKUs: 22503101, 22503111, 22503301, 22503311
OEM outlet or full 3-inch
22503101 / 22503301 have 2-1/2" OEM rear outlets. 22503111 / 22503311 have full 3" outlets and require a matching rear system rather than the factory cat-back.
Match the front header joint
The 304 stainless connections use TORCA Swivel-Seal joints and require matching Kooks long tube headers. Choose for the SS / ZL1 applications in the vehicle table. The full 3-inch Competition Only 22503111 includes TORCA clamps and requires a matching rear system.

Frequently asked questions
Will the full 3-inch versions fit the OEM cat-back?
No. Choose the 2-1/2" OEM-outlet version for that interface.
What changes between the GREEN and Competition choices?
GREEN supplies catted connections. Competition Only is uncatted; the rear-size choice remains a separate decision.
