2-1/2in. Extensions 3in. flng.

The HEDMAN 2-1/2in. Extensions 3in. flng. (part number 18806) is a precision exhaust manifold extension designed for builders and mechanics who need to adapt header systems to non-standard engine bays or custom installation scenarios. These extensions serve as critical transition pieces when your existing manifold or downpipe requires additional length to clear engine-mounted accessories or firewall configurations.

Engineered to bolt directly to standard manifold outlets, these extensions maintain proper exhaust flow characteristics while extending your exhaust routing path. The 3-inch flange ensures a solid, leak-free connection that maintains the structural integrity of your exhaust system under high-temperature conditions and engine vibration. HEDMAN's manufacturing standards guarantee consistent wall thickness and proper alignment, preventing misalignment issues that commonly plague budget alternatives.

These extensions are ideal for various custom fabrication projects, providing a reliable OEM-quality solution. At 6.7 pounds, the extension is lightweight enough for performance applications while retaining the rigidity necessary for long-term durability. Whether you're working with a tight engine bay retrofit or a custom installation, these extensions are designed to meet your needs.
