Wastegate EX44 44mm External

The Wastegate EX44 44mm External from GO FAST BITS is a precision boost-control valve engineered for turbocharged and supercharged engines requiring reliable, adjustable wastegate function. Designed for serious performance tuners and enthusiasts, this external wastegate manages exhaust bypass pressure to prevent boost creep and maintain consistent turbo spool characteristics across varying load conditions. The 44mm port diameter and 15 psi spring rating make it compatible with a wide range of forced-induction applications, from street builds to track-focused platforms.

This wastegate operates by diverting excess exhaust gas around the turbine wheel, preventing overboosting and protecting engine internals from destructive pressure spikes. The EX44's 44mm external design allows it to be mounted remotely from the turbo housing, offering flexible packaging on custom or modified exhaust systems. Black powder-coated finish resists corrosion and thermal degradation in high-temperature exhaust environments. The unit arrives complete with all necessary clamps, flanges, gaskets, and hardware for straightforward installation, eliminating the need for sourcing additional components.

Performance builders and tuners select the Wastegate EX44 when stock or internal wastegate solutions fall short of their boost-management demands. Its universal design integrates into most custom turbo builds, provided exhaust manifold routing accommodates a 44mm external mount. The 15 psi spring rate suits moderate to aggressive boost levels typical in street performance and motorsport applications. Proper sizing and installation—using the included hardware and gaskets for airtight sealing—ensure consistent wastegate response and long-term durability under continuous boost cycling.
