Review MANLEY Master Flo Exhaust Valve fits STREET

The Manley 10721-1 Street Master Flo Exhaust Valve is a high-performance aftermarket exhaust valve designed for racing and high-performance applications. This valve is engineered to provide excellent durability, reliability, and performance gains over OEM exhaust valves.

The Street Master Flo Exhaust Valve features a unique design with a floating valve head, which allows for greater clearance and reduced valve interference with the exhaust port. This results in improved exhaust gas flow and increased power output. The valve is also designed with a large 31.2mm (1.225 inches) diameter, which provides better flow and reduces backpressure.

The valve body is made from high-strength billet aluminum, which provides excellent heat dissipation and durability. The valve stem is made from chrome molybdenum steel, which offers superior strength and resistance to wear and fatigue. The valve seat is made from high-performance ceramic material, which ensures a perfect seal and minimal heat transfer to the head.

The Manley 10721-1 Street Master Flo Exhaust Valve is designed to fit most V8 and V12 engines, making it a versatile choice for a wide range of high-performance applications. It is suitable for use with both natural and forced induction engines, and can be used with both unleaded and leaded fuel.

The valve comes with a detailed installation guide, and is backed by Manley's industry-leading warranty, which covers defects in materials and workmanship for a period of one year from the date of purchase. With its superior design, materials, and construction, the Manley 10721-1 Street Master Flo Exhaust Valve is an excellent choice for any high-performance engine build.
