Product Description

The Vibrant 1460 is a precision laser-cut T304 stainless steel exhaust manifold flange designed for Honda and Acura B-Series four-cylinder engines including the B16A, B17A1, B18A1, B18B1, B18C1, B18C5, B20B4, and B20Z2. At 3/8 in. thick, the flange provides the rigidity needed to maintain a flat, warp-resistant seal against the cylinder head through repeated heat cycling on both naturally aspirated and turbocharged builds. Port sizing is matched to the B-Series head outlet geometry and optimized for standard wall round tubing - the most common tube type used in B-Series custom header fabrication.

The CNC-machined mating surface and precision laser-cut bolt holes ensure accurate alignment to the cylinder head without secondary fitment work. This is one of the most widely used manifold flanges in the Honda and Acura aftermarket, covering the full B-Series engine family across Integra, Civic Si, Del Sol, and CR-V platforms from 1990 through 2001. When welding to stainless tubing, Vibrant recommends 309L filler rod for a strong, corrosion-resistant joint. Sold individually.
