Gen 3 Hemi Billet Header Flanges

Our Gen 3 Hemi Billet Header Flanges are built for serious fabrication and high-performance exhaust setups. Precision CNC machined from premium billet material, these flanges are designed to provide exceptional sealing, strength, and durability for custom header builds on Gen 3 Hemi platforms. Manufactured 100% in America, these flanges are engineered with quality and performance in mind. Each flange features a robust 1/2" thick design to minimize warping under extreme heat and boost conditions while providing a solid mounting surface for long-term reliability. The ports are fully contoured for 2" exhaust primaries, allowing for a smooth transition and improved exhaust flow in naturally aspirated, supercharged, or turbocharged applications. Whether you're building street headers, race headers, or custom turbo manifolds, these billet flanges provide the strength and precision your setup demands.
