Compared With The Alternatives
| Factory cast iron manifolds | Cast iron restricts flow and cracks under heat, this header improves flow and lasts longer |
|---|---|
| Universal cut-to-fit headers | Universal headers require welding and fitment work; this kit bolts on without modification |
Installation
Use Guide
- Confirm the vehicle is a 1998-2002 Camaro Z28, Firebird, or Firebird Trans Am with the LS1 5.7L V8
- Remove the factory manifolds and clean the cylinder head mating surfaces before installing
- Use new gaskets and bolts; do not reuse old components
- Torque flange bolts evenly in a cross pattern to maintain sealing face flatness
- Recheck torque after the first heat cycle to prevent leaks
