Do It Once, Do It Right

Hedman Elite Headers are the best you can buy. They have thicker flanges, stronger tubing, and thermal coating to withstand full-throttle thrashing and torturous towing. Their extreme-duty construction protects against burnout and exhaust leaks caused by the excessive heat and vibration of high-performance applications. Elite Headers outlast and outperform ordinary headers. All Hedman street headers are made in the USA with a 5-year coating warranty and lifetime product defect warranty.

Note: Installing coated headers on an engine during the break-in period will cause discoloration. It is recommended that the factory manifolds or an old set of headers are used while breaking in an engine.

Features

Hefty 3/8" flanges
Shorty or full-length design
Thick wall 14-gauge primary tubes
Built to withstand tough applications
HTC thermal coating with 5-year warranty
Lifetime warranty against manufacturing defects

JEGS Easy Kits are designed by JEGS high performance racing professionals to help you get all the performance parts you need for your race car, hot rod or truck.
