Big Block Mopar (383-440) Round Port 1/2" Thick Stainless Turbo Header Flange

Precision laser cut form 1/2" thick 304 Stainless Steel, our turbo header flanges are manufactured in the U.S. and are machine surfaced. These turbo header flanges are specifically made for stock port 383-440 CID Mopar engines.

Port Size: 2" round port

The 2" port works great for thick wall tubing or schedule pipe on a turbo build requiring a smaller inner diameter for exhaust velocity to minimize turbo lag, and a large outside diameter to allow for thicker material.

We carry over 300 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.

Flanges sold separately.
