Description

Enhance your classic 1955-1957 Chevy's performance with Hedman's 55-57 Chevy Passenger headers. Crafted from durable mild steel with a temporary black paint finish, these full-length headers feature 1.75-inch primary tubes and 3-inch ball-and-socket collectors, ensuring optimal exhaust flow and increased horsepower. The package includes headers, ball-and-socket reducers, gaskets, and mounting hardware for a comprehensive installation. Please note, the temporary paint is designed to protect the headers during shipping and is not intended as a final finish; it is recommended to apply a high-temperature coating before use. These headers are not legal for street use on '75-later model years and are intended for off-road use only.

Disclaimer

The temporary paint applied to these headers is not designed as a final finish and will not withstand high heat associated with engine operation. It is recommended to strip this coating and apply a high-temperature paint or coating designed for use on headers. These headers are not legal for street use on '75-later model years and are intended for off-road use only.
