Go Fast Bits EX44 Universal 44mm V-Band Style External style Wastegate (GFB 7002)

GFB EX44 44mm External Wastegate | 7002

Take control of boost pressure with the Go Fast Bits EX44 44mm External Wastegate. Engineered for high-performance turbocharged applications, this compact V-band wastegate combines exceptional exhaust flow, precise boost control, and premium materials in one of the smallest external wastegate designs in its class.

Manufactured in Australia, the EX44 features an investment cast 253MA chromium-nickel stainless steel body engineered to withstand extreme exhaust temperatures. A precision-machined stainless steel valve and Nomex-reinforced silicone diaphragm provide the durability and consistent operation needed for demanding street, track, and high-horsepower turbo applications.

With an overall height of just 100mm, the EX44 is ideal for tight engine bays and custom turbo manifolds where space is limited. Its V-band mounting system is directly compatible with TiAL MV-R wastegate flanges, making it an excellent option for new turbo builds or replacing an existing compatible external wastegate.

Key Features

• 44mm external wastegate for turbocharged applications
• Compact 100mm overall height
• Investment cast 253MA chromium-nickel stainless steel body
• CNC-machined stainless steel valve and seat
• CNC-machined billet 6061 aluminum actuator housing
• High-temperature Nomex-reinforced silicone diaphragm
• Internal valve stem shroud reduces heat exposure and carbon buildup
• V-band inlet and outlet connections
• Directly compatible with TiAL MV-R weld-on flanges
• Multiple wastegate spring pressure configurations
• Made in Australia under ISO 9001 quality standards
• GFB part number 7002

Adjustable Wastegate Spring Pressure

The GFB EX44 includes a 10 PSI outer spring and a 5 PSI inner spring, allowing you to configure the wastegate for different base boost pressures depending on your turbo setup.

• 5 PSI using the supplied inner spring
• 10 PSI using the supplied outer spring
• 15 PSI using both supplied springs together

An optional 7 PSI middle spring is available separately. By combining the available springs, the EX44 supports nominal base boost pressures of 5, 7, 10, 12, 15, 17, and 22 PSI.

Actual boost pressure may vary depending on the turbocharger, exhaust manifold design, engine configuration, and boost control system.

High Temperature Stainless Steel Construction

Unlike conventional wastegates, the GFB EX44 uses a 253MA stainless steel body specifically suited for extreme exhaust environments. The precision-machined valve, high-temperature hardware, and reinforced silicone diaphragm are designed to provide dependable operation under repeated heat cycles and demanding boost conditions.

An internal shroud helps shield the valve stem from excessive heat and carbon deposits, reducing the risk of sticking and supporting consistent wastegate operation.

Compact Design & V-Band Compatibility

The EX44 features a compact 100mm overall height, allowing installation in tight engine bays and custom turbo setups where larger external wastegates may be difficult to package.

Its V-band inlet and outlet design allows straightforward installation and removal. The EX44 is also directly compatible with TiAL MV-R weld-on flanges, making it a versatile solution for existing turbo systems using compatible mounting hardware.

What's Included

• One assembled GFB EX44 44mm External Wastegate
• One 10 PSI outer spring
• One 5 PSI inner spring
• Two V-band clamps
• Two 1/8 inch BSPT hose fittings
• One stainless steel inlet weld-on flange (GFB 7052)
• One stainless steel outlet weld-on flange (GFB 7042)

Universal Applications

The GFB EX44 is designed for universal turbocharged applications requiring a 44mm external wastegate. It is suitable for custom turbo manifolds, aftermarket turbo kits, and performance builds using compatible TiAL MV-R style wastegate connections.

• Custom turbocharger systems
• High horsepower street builds
• Drag racing applications
• Track and motorsport vehicles
• Custom exhaust manifold fabrication
• Existing turbo systems using TiAL MV-R compatible flanges

Important Installation Information

Professional installation and proper boost control configuration are recommended. The inlet weld-on flange is best suited for 2 inch outside diameter exhaust tubing with a minimum 0.120 inch wall thickness or compatible 1.5 inch nominal bore Schedule 10 piping.

The outlet flange is designed for 1.75-inch outside diameter tubing. Always verify your turbo manifold configuration, wastegate placement, and spring pressure requirements before installation.
