Complete the Kooks front exhaust on your LT1 F-body
These Kooks Y-pipes join matching long tube headers to the OEM rear exhaust point on your 1993-1997 Camaro or Firebird LT1. Choose uncatted Competition Only or Performance cats for a naturally aspirated engine, with 3" front tubing and 2-3/4" rear outlets.
SKUs: 22403100, 22403200
Keep the LT1 exhaust family matched
The 5.7-litre LT1 installation uses its own headers and front connection arrangement. The later LS1 Camaro / Firebird range is a different exhaust application.
Choose your catalyst option
22403100 is the uncatted Competition Only choice. 22403200 uses Performance cats for naturally aspirated engines. Both require matching Kooks LT1 long tube headers and use the 2-3/4-inch OEM rear interface.
