Product Description

The Vibrant 14296 is a pair of precision laser-cut T304 stainless steel exhaust manifold flanges designed for the Porsche 996-generation 911 M96 flat-6 engine. At 3/8 in. thick, the flanges provide the rigidity needed to maintain a flat, warp-resistant seal against the cylinder head through repeated heat cycling - critical for performance builds on these high-revving naturally aspirated and turbocharged flat-six platforms. Port sizing is matched to the 996/911 head outlet geometry and optimized for standard wall round tubing.

The CNC-machined mating surface and precision laser-cut bolt holes ensure accurate alignment to the cylinder head without secondary fitment work. These flanges are compatible with all 996-generation 911 variants including Carrera, Carrera S, Turbo, GT2, and GT3. When welding to stainless tubing, Vibrant recommends 309L filler rod for a strong, corrosion-resistant joint. Sold as a pair covering both cylinder banks for a complete header or manifold fabrication set.
