Mopar 6.1L Hemi Mild Steel Header Flange

Precision laser cut form 3/8" thick mild steel, our header flanges are manufactured in the U.S. and are machine surfaced. This D-port header flange is designed on the 6.1/6.2/6.4L late-model "Eagle" hemi cylinder heads. Earlier model gen III hemi heads will typically have a round or square exhaust port, though bolt patterns remain the same.

Port Size: 2" and 2 1/8" Port sizes available

Preformed Flange Stubs are 2"-3" in length, and are formed to perfectly fit the non-round port in the flange. Stubs drastically reduce overall build time and increase builder's efficiency.

We carry over 250 different header flange designs, so if you don't see the flange you're looking for, talk with one our tech reps about custom header flange cutting.
