The Go Fast Bits (GFB) EX38 38mm External Wastegate is the ultimate solution for compact, high-performance turbo systems. Featuring an investment-cast 253MA stainless steel body, this unit is designed to handle the intense heat generated by high-boost applications. The EX38 is engineered for longevity, utilizing a nomex-reinforced diaphragm and a high-flow stainless steel valve to ensure consistent boost pressure regulation under the most demanding conditions.

Key Features and Benefits

  • Universal Fitment: V-Band inlet and outlet, directly compatible with TiAL MV-S flanges.
  • Compact Footprint: 93mm overall height, perfect for tight manifold clearances.
  • Spring Versatility: Supplied with 10PSI outer spring; compatible with 5PSI and 7PSI springs for custom tuning.
  • Tunable Boost: Achieve base pressures from 5PSI to 22PSI through various spring configurations.

The EX38 provides tuners with the ability to fine-tune their base boost levels, ensuring that your turbocharger operates within its optimal efficiency range. Whether you are upgrading your current setup or building a new turbo system from scratch, the GFB EX38 offers the build quality and reliability needed for serious performance. Its robust design minimizes the risk of diaphragm failure and valve sticking, common issues in lower-quality wastegates. Elevate your vehicle's performance with premium components from GGCRACING.
