1UZ Exhaust Header Flanges – 3/8" Steel (Pair)

These 1UZ Exhaust Header Flanges are designed to simplify custom exhaust and header fabrication by eliminating the hassle of cutting up factory flanges or aligning multiple separate pieces. CNC-cut from thick steel, these one-piece flanges provide a clean, accurate foundation for building custom headers with improved fitment and weldability.

One-Piece Flange Design: Replaces the factory multi-piece exhaust flange layout, making header fabrication faster, easier, and more precise.

3/8" Thick Steel Construction: Made from heavy-duty 3/8" steel to resist warping during welding and high-heat exhaust operation.

Fabrication-Friendly Fitment: Designed for accurate port alignment and easier header tube placement compared to modifying OEM flanges.

Ideal for Custom Headers: Perfect for turbo builds, NA performance setups, and engine swap projects using the 1UZ platform.

Cleaner Final Result: One-piece design ensures better alignment and a more professional-looking finished header.

Sold as a Pair: Includes both left and right exhaust flanges for a complete engine set.

Important Notes:

  • Intended for custom fabrication use

  • Welding required

  • Exhaust headers not included

Engine Fitment:

  • Toyota / Lexus 1UZ-FE engines

Disclaimer:
Fabrication experience is required. Professional welding and fitment are recommended for best results.

Why Choose These 1UZ Exhaust Flanges?:
Stronger, easier to work with, and far more precise than modified factory flanges, these 1UZ one-piece exhaust flanges are the right starting point for clean, professional header fabrication.
