The Japspeed Stainless Steel 4-2-1 Exhaust Manifold is designed to improve exhaust flow and engine performance on Honda Civic models equipped with B16 1.6 and B18 1.8 engines.
Replacing the restrictive factory exhaust manifold with a free-flowing tubular design allows exhaust gases to exit the engine more efficiently, helping improve throttle response and support increased power output.
Manufactured from high-quality T304 stainless steel, this CAD-designed manifold features a 4-2-1 configuration, which is designed to deliver improved mid-range torque and power compared with a conventional 4-1 manifold.
The manifold incorporates a 2-inch bore collector to promote efficient exhaust gas flow, while TIG-welded construction provides strength and durability.
Designed for direct bolt-on installation, the manifold connects to the standard catalytic converter or a compatible aftermarket sports catalytic converter or decat pipe. Gaskets are included for installation.
