Description

If you think you are tough on your performance parts, but stainless is not in your budget, then Hedman Elite extreme-duty headers may be the right fit for you project. Their heavier duty construction takes the punishment, and their quality design dishes out the power! They feature thick wall 14-gauge mild steel primary tubes with 3/8 in. flanges to prevent warping for a longer lasting, leak-free seal. Hedman Elite extreme-duty headers are available with the matte silver or Black Maxx ceramic coatings that withstand temperatures up to 1,400 degrees F.
