Installation Notes
The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty.

If you have any questions about this or any FlowTech application, please contact our tech service department at 270-781-9741.
